While optimizing atomic coordinates of a magnetic system, I noticed that magnetic moment per cell changes with lattice constant. For this reason I want to fix moment at first, then make optimization calculations for different lattice constants. Repeating this procedure for different moments, I obtain different magnetic branches of the structure. The branch with minimum energy configuration will be ground state, I assume.
