Abstract

Structural and magnetic properties have been studied in perovskite Nd_1-xEr_xMnO₃ (0 ≤ x ≤ 0.5). Er³⁺ doping enhances the Jahn-Teller distortion, strongly affects the Nd³⁺-Mn³⁺ interaction, destroys the intermediate state below the antiferromagnetic transition temperature in NdMnO₃, and breaks the antiparallel arrangement between Nd³⁺ and Mn³⁺ spin ordering. The decreasing ferromagnetic component in magnetic hysteresis loops at 30 K indicates that the canted angles vary with x. These results offer strong evidence for the interaction between rare earth ions and transition metal ions and competition among rare earth ions as well.
