摘要：

We have used the magnetocaloric effect (MCE) to investigate the modifications of the cluster-glass transitions detected at temperatures above the ferromagnetic ground state in some representative CeNi1-xCux compositions (0.2 <= x <= 0.6). The MCE was calculated from heat-capacity data measured in fields up to 90 kOe and temperature down to 500 mK. The observed evolution of MCE along the series is discussed considering hybridization effects. (c) 2006 Elsevier B.V. All rights reserved.
