|

|

The magnetic spin simualtions are enabled by the SPIN package, whose
|
||||
implementation is detailed in "Tranchida"_#Tranchida7.
|
||||
|
||||
The model representents the simulation of atomic magnetic spins coupled
|
||||
to lattice vibrations. The dynamics of those magnetic spins can be used
|
||||
to simulate a broad range a phenomena related to magneto-elasticity, or
|
||||
or to study the influence of defects on the magnetic properties of
|
||||
materials.
|
||||
|
||||
The magnetic spins are interacting with each others and with the
|
||||
lattice via pair interactions. Typically, the magnetic exchange
|
||||
interaction can be defined using the
|
||||
"pair/spin/exchange"_pair_spin_exchange.html command. This exchange
|
||||
applies a magnetic torque to a given spin, considering the orientation
|
||||
of its neighboring spins and their relative distances.
|
||||
It also applies a force on the atoms as a function of the spin
|
||||
orientations and their associated inter-atomic distances.
|
||||
|
||||
The command "fix precession/spin"_fix_precession_spin.html allows to
|
||||
apply a constant magnetic torque on all the spins in the system. This
|
||||
torque can be an external magnetic field (Zeeman interaction), or an
|
||||
uniaxial magnetic anisotropy.
|
||||
|
||||
A Langevin thermostat can be applied to those magnetic spins using
|
||||
"fix langevin/spin"_fix_langevin_spin.html. Typically, this thermostat
|
||||
can be coupled to another Langevin thermostat applied to the atoms
|
||||
using "fix langevin"_fix_langevin.html in order to simulate
|
||||
thermostated spin-lattice system.
|
||||
|
||||
The magnetic Gilbert damping can also be applied using "fix
|
||||
langevin/spin"_fix_langevin_spin.html. It allows to either dissipate
|
||||
the thermal energy of the Langevin thermostat, or to perform a
|
||||
relaxation of the magnetic configuration toward an equilibrium state.
|
||||
|
||||
All the computed magnetic properties can be outputed by two main
|
||||
commands. The first one is "compute spin"_compute_spin.html, that
|
||||
enables to evaluate magnetic averaged quantities, such as the total
|
||||
magnetization of the system along x, y, or z, the spin temperature, or
|
||||
the magnetic energy. The second command is "compute
|
||||
property/atom"_compute_property_atom.html. It enables to output all the
|
||||
per atom magnetic quantities. Typically, the orientation of a given
|
||||
magnetic spin, or the magnetic force acting on this spin.

[Description:]
|
||||
|
||||
Define a computation that calculates the pair entropy fingerprint for
|
||||
each atom in the group. The fingerprint is useful to distinguish between
|
||||
ordered and disordered environments, for instance liquid and solid-like
|
||||
environments, or glassy and crystalline-like environments. Some
|
||||
applications could be the identification of grain boundaries, a
|
||||
melt-solid interface, or a solid cluster emerging from the melt.
|
||||
The advantage of this parameter over others is that no a priori
|
||||
information about the solid structure is required.
|
||||
|
||||
This parameter for atom i is computed using the following formula from
|
||||
"(Piaggi)"_#Piaggi and "(Nettleton)"_#Nettleton ,
|
||||
|
||||
:c,image(Eqs/pair_entropy.jpg)
|
||||
|
||||
where r is a distance, g(r) is the radial distribution function of atom
|
||||
i and rho is the density of the system. The g(r) computed for each
|
||||
atom i can be noisy and therefore it is smoothened using:
|
||||
|
||||
:c,image(Eqs/pair_entropy2.jpg)
|
||||
|
||||
where the sum in j goes through the neighbors of atom i, and sigma is a
|
||||
parameter to control the smoothening.
|
||||
|
||||
The input parameters are {sigma} the smoothening parameter, and the
|
||||
{cutoff} for the calculation of g(r).
|
||||
|
||||
If the keyword {avg} has the setting {yes}, then this compute also
|
||||
averages the parameter over the neighbors of atom i according to:
|
||||
|
||||
:c,image(Eqs/pair_entropy3.jpg)
|
||||
|
||||
where the sum j goes over the neighbors of atom i and N is the number
|
||||
of neighbors. This procedure provides a sharper distinction between
|
||||
order and disorder environments. In this case the input parameter
|
||||
{cutoff2} is the cutoff for the averaging over the neighbors and
|
||||
must also be specified.
|
||||
|
||||
If the {avg yes} option is used, the effective cutoff of the neighbor
|
||||
list should be {cutoff}+{cutoff2} and therefore it might be necessary
|
||||
to increase the skin of the neighbor list with:
|
||||
|
||||
neighbor skin bin :pre
|
||||
|
||||
See "neighbor"_neighbor.html for details.
|
||||
|
||||
If the {local yes} option is used, the g(r) is normalized by the
|
||||
local density around each atom, that is to say the density around each
|
||||
atom is the number of neighbors within the neighbor list cutoff divided
|
||||
by the corresponding volume. This option can be useful when dealing with
|
||||
inhomogeneus systems such as those that have surfaces.
|
||||
|
||||
Here are typical input parameters for fcc aluminum (lattice
|
||||

|
||||

||||

|

|
||||
|
||||
[Output info:]
|
||||
|
||||
By default, this compute calculates the pair entropy value for each
|
||||
atom as a per-atom vector, which can be accessed by any command that
|
||||
uses per-atom values from a compute as input. See "Section
|
||||
6.15"_Section_howto.html#howto_15 for an overview of LAMMPS output
|
||||
options.
|
||||
|
||||
The pair entropy values have units of the Boltzmann constant. They are
|
||||
always negative, and lower values (lower entropy) correspond to more
|
||||
ordered environments.

[Description:]
|
||||
|
||||
Define a computation that calculates magnetic quantities for a system
|
||||
of atoms having spins.
|
||||
|
||||
This compute calculates 6 magnetic quantities.
|
||||
|
||||
The three first quantities are the x,y and z coordinates of the total magnetization.
|
||||
|
||||
The fourth quantity is the norm of the total magnetization.
|
||||
|
||||
The fifth quantity is the magnetic energy.
|
||||
|
||||
The sixth one is referred to as the spin temperature, according
|
||||
to the work of "(Nurdin)"_#Nurdin1.
|
||||
|
||||
The simplest way to output the results of the compute spin calculation
|
||||
is to define some of the quantities as variables, and to use the thermo and
|
||||
thermo_style commands, for example:
|
||||
|
||||
compute out_mag all compute/spin :pre
|
||||
|
||||
variable mag_z equal c_out_mag\[3\]
|
||||
variable mag_norm equal c_out_mag\[4\]
|
||||
variable temp_mag equal c_out_mag\[6\] :pre
|
||||
|
||||
thermo 10
|
||||
thermo_style custom step v_mag_z v_mag_norm v_temp_mag :pre
|
||||
|
||||
This serie of commands evaluates the total magnetization along z, the norm of
|
||||
the total magnetization, and the magnetic temperature. Three variables are
|
||||
assigned to those quantities. The thermo and thermo_style commands print them
|
||||
every 10 timesteps.
|
||||
|
||||
|
||||
[Output info:]

[Examples:]

|
||||
[Description:]
|
||||
|
||||
Apply a Langevin thermostat as described in "(Mayergoyz)"_#Mayergoyz1 to the
|
||||
magnetic spins associated to the atoms.
|
||||
Used with "fix nve/spin"_fix_nve_spin.html, this command performs
|
||||
Brownian dynamics (BD).
|
||||
A random torque and a transverse dissipation are applied to each spin i according to
|
||||
the following stochastic differential equation:
|
||||
|
||||
:c,image(Eqs/fix_langevin_spin_sLLG.jpg)
|
||||
|
||||
with lambda the transverse damping, and eta a random verctor.
|
||||
This equation is referred to as the stochastic Landau-Lifshitz-Gilbert (sLLG)
|
||||
equation.
|
||||
|
||||
The components of eta are drawn from a Gaussian probability law. Their amplitude
|
||||
is defined as a proportion of the temperature of the external thermostat T (in K
|
||||
in metal units).
|
||||
|
||||
More details about this implementation are reported in "(Tranchida)"_#Tranchida2.
|
||||
|
||||
Note: due to the form of the sLLG equation, this fix has to be defined just
|
||||
before the nve/spin fix (and after all other magnetic fixes).
|
||||
As an example:
|
||||
|
||||
fix 1 all precession/spin zeeman 0.01 0.0 0.0 1.0
|
||||
fix 2 all langevin/spin 300.0 0.01 21
|
||||
fix 3 all nve/spin lattice yes :pre
|
||||
|
||||
is correct, but defining a force/spin command after the langevin/spin command
|
||||
would give an error message.
|
||||
|
||||
Note: The random # {seed} must be a positive integer. A Marsaglia random
|
||||
number generator is used. Each processor uses the input seed to
|
||||
generate its own unique seed and its own stream of random numbers.
|
||||
Thus the dynamics of the system will not be identical on two runs on
|
||||
different numbers of processors.

[Description:]
|
||||
|
||||
Perform a symplectic integration for the spin or spin-lattice system.
|
||||
|
||||
The {lattice} keyword defines if the spins are integrated on a lattice
|
||||
of fixed atoms (lattice = no), or if atoms are moving (lattice = yes).
|
||||
|
||||
By default (lattice = yes), a spin-lattice integration is performed.
|
||||

The {nve/spin} fix applies a Suzuki-Trotter decomposition to
|

the equations of motion of the spin lattice system, following the scheme:
|

|

:c,image(Eqs/fix_integration_spin_stdecomposition.jpg)
|
||||
|

according to the implementation reported in "(Omelyan)"_#Omelyan1.
|

A sectoring method enables this scheme for parallel calculations.

To use the spin algorithm, it is necessary to define a map with

Impose a force torque to each magnetic spin in the group.

|
||||
magnetic field:
|
||||
|
||||
:c,image(Eqs/force_spin_zeeman.jpg)

with mu0 the vacuum permeability, muB the Bohr magneton (muB = 5.788 eV/T

in metal units).
|

Style {anisotropy} is used to simulate an easy axis or an easy plane

for the magnetic spins in the defined group:

:c,image(Eqs/force_spin_aniso.jpg)
|
||||
|
||||
with n defining the direction of the anisotropy, and K (in eV) its intensity.
|
||||
If K>0, an easy axis is defined, and if K<0, an easy plane is defined.
|
||||
|
||||
In both cases, the choice of (x y z) imposes the vector direction for the force.
|
||||
Only the direction of the vector is important; it's length is ignored.

Both styles can be combined within one single command line.

For the {format} style, an equal-style variable is specified along

appropriate for formatting a double-precision floating-point value.
