摘要：

The magnetic properties and magnetocaloric effects (MCEs) in La0.8R0.2(Fe0.919Co0.081)(11.7)Al-1.3 (R = Pr, Nd) compounds have been investigated. When Pr and Nd substitute for La, the Curie temperature of compounds decreases. The values of the MCEs are enhanced significantly by a partial substitution of Nd for La. Under the field change of 2 and 5 T, the maximum magnetic entropy changes for La0.8Nd0.2 (Fe0.919Co0.081)(11.7)Al-1.3 compound are -4.56 and -9.46 J/Kg K, respectively. It can be exploited for room temperature magnetic refrigeration material. (C) 2008 Elsevier B.V. All rights reserved.
