摘要：

A"hole" is found to develop in the dc field-dependent ac susceptibility of CuMn spin glasses when the material is cooled or aged in a field. Comparisons are made with analogous experiments on structural glasses at low temperature. The hole is not compatible with independent two-level systems. The significance of the width (in H) of this hole is discussed.
