摘要：
The first-order phase transitions in NdFe12B6 and PrFe12B6 alloys give rise to giant values of magnetic entropy changes in relatively low field. However, the metastable nature of these alloys associates with a special procedure of preparation and considerable amount of impurities inevitably. By alloying NdFe12B6 with the iso-structural compound of NdCo12B6 appropriately, a Nd(Co1 - xFex)(12)B-6 system which possesses the stable SrNi12B6-type structure can be obtained directly via the standard casting-and-annealing method. Remarkably improved thermal and magnetic reversibility are observed in the present system. The second-order phase transitions in NdCo12B6 alloy give rise to the relative cooling power, which is comparable with that of NdFe12B6 alloy around the ordering temperature. (C) 2011 Elsevier B.V.
