Abstract
The itinerant-electron metamagnetic (IEM) transition and magnetocaloric effects (MCEs) in cubic NaZn13-type La1-zCe z(Fe0.88Si0.12)13 with z = 0.0, 0.1, 0.2 and 0.3 have been investigated. By partial substitution of Ce for La, the Curie temperature TC decreases with decreasing the lattice constant. In addition, the isothermal magnetic entropy change ΔSm and the adiabatic temperature change ΔTad due to the IEM transition are enhanced because of the increase of the entropy change caused by the latent heat. Therefore, the partial substitution of Ce for La in La(Fe xSi1-x)13 is highly effective in the enhancement of MCEs.
