The equiatomic Fe-Co alloy is an ideal soft magnetic material due to the combination of high saturation magnetization, permeability and low coercivity it offers. The ordered B2 phase in it, however, makes it highly brittle and hence unsuitable for industrial-scale manufacturing of bulk soft magnets....
