Abstract

The single phase of a cubic NaZn₁₃-type La_1-zNd _z(Fe_0.88Si_0.12)₁₃ is obtained in the region z ≤ 0.2. The field-induced first-order transition from the paramagnetic to ferromagnetic state, that is, the itinerant-electron metamagnetic (IEM) transition is kept after the substitution of Nd. In addition, a discontinuous change of magnetization at the Cure temperature becomes larger with increasing z. As a result, the isothermal magnetic entropy change and the relative cooling power in the magnetic field change from 0 to 5 T increase to -27 J/kg K and 518 J/kg, respectively, by the partial substitution of z = 0.2.
