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.

Magnetic Phases

The magnetic susceptibility measurements have been made on antiferromagnetic compounds Mn1–xFexSn2 and the magnetic phase diagram was illustrated. The high temperature magnetic phases I and III, major phases, were analyzed on the basis of molecular field theory and explained the change of magnetic structure I⇌III occured at x≈0.8.
