Abstract
The dynamic susceptibility chi ( omega , T, H) is calculated for an Ising spin glass with infinite-range interactions for small frequencies, omega , and a large range of temperatures and fields. The observed sharp increase of the imaginary part Im chi (T) near the freezing temperature Tf for small and vanishing fields is explained by the crossover from Im chi varies as omega at high temperatures to Im chi varies as omega 1/2 at Tf. At low temperatures, Im chi increases in proportion to T.Keywords
