Random Magnetic Anisotropy

The model of Harris, Plischke, and Zuckermann for random magnetic anisotropy in amorphous alloys is examined in the molecular field approximation for the case of antiferromagnetic exchange coupling. The existence of spin-flop transitions and a spin-glass-like magnetic susceptibility is established by numerical calculation. The results are discussed in connection with current theoretical and experimental work.
