摘要：

The linearized magnetic excitations (magnons) in a two-dimensional +/-J Heisenberg spin glass are investigated in the limit where the field is assumed to be strong enough to set up complete alignment of the ground state. The density of states, the localization indices, and the dynamic structure factor at zero temperature are computed by numerical simulation techniques. A comparison is made between the numerical results for the density of states and the dynamic structure factor and the predictions of the coherent-exchange approximation. Numerical results at zero field are also presented.
