Abstract
A mean-field model of a Heisenberg spin-glass with weak random anisotropy is solved. It is shown that an Ising-like phase transition in a finite magnetic field occurs at in the limit of small . The crossover to an Ising behavior occurs when , where and are the anisotropy and exchange coupling constants, respectively.
