Predict local moments for a few collinear seeds and rank them by energy: ferromagnetic, a two-sublattice antiferromagnet when the cell has one magnetic element, and ferrimagnetic patterns that oppose one element when several are present. Saturation magnetization is the aligned ferromagnetic moment divided by the cell volume. Ground-state magnetization uses the net moment of the lowest ordering, so an antiferromagnetic winner is near zero. This is a short collinear menu, not a magnetic space-group search.
