Abstract
B-site substitution effects on the structural and magnetic properties are investigated in Nd1/2Ca1/2(Mn0.97M0.03) O3 (M = Al, Zn, Sc, Fe, Ni, Co, and Cr). With decreases of temperature below ∼200 K, these compounds transform into a two-phase state. With further decrease of temperature below ∼100 K, the Cr-, Co-, and Ni-doped compounds show the ferromagnetic transition, while the other compounds show only the antiferromagnetic component. We discuss these dopant-dependent ferromagnetic transition in terms of the effective one-electron bandwidth of the e g band.
