Abstract

We have scaled up the production process of magnetic refrigerants near room temperature. The Mn2−yFeyxRuxP1−zSiz compounds with 0.03 ≤ x ≤ 0.16, y ≈ 0.75, and z ≈ 0.55 were synthesized and their magnetocaloric properties were examined. By changing the compositions and the annealing temperature, the Curie temperature was tuned between 275 and 315 K with 2~3 K steps. All the compounds underwent a first-order magnetic transition accompanied by thermal hysteresis of less than 2 K. The compounds showed excellent magnetocaloric properties: the magnetic entropy change was more than 10 J/K·kg and the refrigerant capacity was about 115 J/kg in a field change of 1.5 T. The detailed instructions to synthesize high-performance (MnFe)2PSi materials are given. View Full-Text
