A theory for an Ising spin glass with random anisotropy

Ivan  da Cunha Lima

Abstract

The Ghatak and Sherrington theory for an Ising spin glass was extended for random anisotropy. The susceptibility and specific heat were calculated using a Gaussian distribution of probability for the magnitude of the random anisotropy. This effect shows a cusp in the susceptibility but not in the specific heat.
