摘要：

Ac-susceptibility measurements at various temperatures and hysteresis studies at various fields indicate that the system Ge//xCu//1// minus //xFe//2O//4(x less than equivalent to 0. 6) contains mixed multidomain, single domain or superparamagnetic states. Sharp susceptibility maxima, resembling those of spin glasses, are observed for x equals 0. 1 and 0. 2, which may be attributed to the single domain-superparamagnetic (SD-SP) transition and the overall behavior shows a cluster spin glass type of ordering.
