摘要：
We report the results of Cole-Cole plot analysis of the AC susceptibility in the spin-glass system NiC(2)O4 . 2(2MIz)(0.49)(H2O)(0.51)(2MIz = 2-methylimidazole). We have found the median relaxation time does not change much below the spin-glass temperature T-G and changes drastically above T-G. The difference of relaxation times between this system and Er0.2Sr0.8S spin-glass one is also discussed. (C) 1998 Elsevier Science B.V. All rights reserved.
