摘要：
A magnetic material for magnetic refrigeration has a composition represented by (R11-yR2y)xFe100-x (R1 is at least one of element selected from Sm and Er, R2 is at least one of element selected from Ce, Pr, Nd, Tb and Dy, and x and y are numerical values satisfying 4≦x≦20 atomic % and 0.05≦y≦0.95), and includes a Th2Zn17 crystal phase, a Th2Ni17 crystal phase, or a TbCu7 crystal phase as a main phase.
