摘要：

The Cox Ga1-x alloys having CsCl structure contain nonmagnetic Co and Ga atoms (host) and magnetic Co atoms (impurities) for x ≳ 0.50. We report here the simultaneous observation of the applied field NMR of host nuclei and the zero field resonance (ZFR) of impurity nuclei. From the ac susceptibility measurements and the field dependence of ZFR signals we conclude that for 0.50 ≲ × ≲ 0.64, this system is a cluster spin glass". © 1979."
