Title: Role of quantum fluctuations in a spin glass

Abstract

The mean-field theory of a quantum Heisenberg spin glass is performed using the variational approach and the replica method. For spin /sup 1///sub 2/, there is no spin glass phase. For 1 equal to or less than s less than infinity, a spin glass phase may exist for T/sub 1/ less than T equal to or less than T/sub f/, where T/sub f/ is the freezing temperature, and at T/sub 1/ the system exhibits a first-order transition back to the paramagnetic state.
