摘要：

A.c. magnetic susceptibility of amorphous holmium aluminosilicate has been measured in the temperature range 0.32-80 K and at various measuring frequencies v. Spin freezing is observed at low temperature (Tf ≅ 0.6 K) and Tf-1 is a linear function of log v in agreement with the model of superparamagnetic clusters. Holmium aluminosilicate may be considered as a dipolar spin-glass. © 1979.
