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.

Temperature Range

Measurements of the magnetic susceptibility of a powdered sample of VTe in the temperature range 90 - 700 K, and of the a.c. electrical conductivity (σ), thermoelectric power (θ) and dielectric constant (ε′) of pressed pellets of the compound in the temperature range 300 -1100 K are reported. The compound is found to be antiferromagnetic with Neel temperature 420 ± 5 K. The effective paramagnetic moment and paramagnetic Curie temperature are found to be 1.6 μB and - 250 K, respectively. The dependence of σ, θ and ε′ on temperature shows no anomaly at the Neel temperature and is indicative of the metallic nature of the compound.
