摘要
MnFe(P,As) displays a large magnetocaloric effect around room temperature. Substitution of Cr for Fe results in a reduction of both the ordering temperature and the magnetocaloric effect. Substitution of Co for Fe leads to a decrease of the ordering temperature, whereas 10% extra Fe substituted for Mn leads to an increase of the ordering temperature. Finally. 10% extra Mn substituted for Fe results in an enhanced magnetocaloric effect with hardly any change of ordering temperature. (C) 2003 Elsevier B.V. All rights reserved.
