Abstract
Magnetic entropy changes of the NdFe12B6 compound, which was crystallized from amorphous as-quenched ribbons, were investigated. Differential thermal analysis shows that it is stable below 940K. An abrupt change of magnetization was observed around its Curie temperature of 218K. The maximum values of magnetic entropy change of this compound are 8.4 and 5.4J∕kgK for the applied fields of 10 and 7kOe, respectively. These results suggest that this ternary compound can be considered as a good candidate for magnetic refrigeration.
