| description | Provided is a magnetic refrigeration material which has a Curie temperature of not lower than 250 K, and provides refrigeration performance well over that of conventional materials when subjected to a field change up to 2 Tesla, which is assumed to be achievable with a permanent magnet. The magnetic refrigeration material is of a composition represented by the formula La1 fREf (Fe1 a b c d eSiaCobXcYdZe)13 (RE: at least one of rare earth elements including Sc and Y and excluding La; X: Ga and/or Al; Y: at least one of Ge, Sn, B, and C; Z: at least one of Ti, V, Cr, Mn, Ni, Cu, Zn, and Zr; 0.03 a 0.17, 0.003 b 0.06, 0.02 c 0.10, 0 d 0.04, 0 e 0.04, 0 f 0.50), and has an average crystal grain size of not smaller than 0.01 μm and not larger than 3 μm, a Curie temperature of not lower than 250 K, and the maximum (− Smax) of magnetic entropy change (− SM) when subjected to a field change up to 2 Tesla is not less than 5 J/kgK. |
