Abstract
A microscopic theory will be developed for the electron-spin resonances (ESR) in spin-glasses with remanence and anisotropy. The model consists of spin vectors randomly distributed and interacting through a dominant exchange interaction and a smaller anisotropic interaction of the Dzyaloshinski-Moriya type. The resulting ESR frequencies are in agreement with recent experimental findings on CuMn. The theory also yields a microscopic foundation for the anisotropy constant used in a recent phenomenological description.Keywords
