摘要：
Polycrystalline Cu-Zn ferrites substituted with different rare-earth ions (R = La, Nd, Sm, and Gd) are investigated. The initial permeability and homogeneity increased for samples with R = Nd, Sm, and Gd relative to the unsubstituted one (US). On the other hand, the magnetization and energy loss are decreased for all substituted samples. The electrical resistivity increased only for samples with R = La and Nd relative to US.
