 The command "fix setforce/spin"_fix_setforce.html allows to set the 
 components of the magnetic precession vectors (while erasing and

+replacing the previously computed magnetic precession vectors on 
 the atom). 
 This command can be used to freeze the magnetic moment of certain 
 atoms in the simulation by zeroing their precession vector. 
 
 The command "fix nve/spin"_fix_nve_spin.html can be used to
