摘要：

A computer investigation of the ground state of a Heisenberg spin glass has indicated the existence of localised clusters of spins which may exist in more than one equilibrium configuration. This indicates the presence of two-level systems. Estimates of the size of a cluster and the energy associated with change in orientation are given.
