Abstract
Effect of Zn doping on the structural and magnetic properties of NdMnO3 has been investigated by neutron diffraction and dc magnetic susceptibility measurements. The partial replacement of Mn3+ by Zn2+ results in the decrease in TN. In the temperature dependent magnetization measurements, a broad hump and a sharp peak has been observed around ~ 50Â K and 10Â K respectively for both the samples. Thermal hysteresis in magnetization between cooling and heating runs indicate first-order phase transition. Magnetization measurements on NdMn0.95Zn0.05O3 sample clearly show that, 5% Zn-doping in NdMnO3 results in the suppression in magnetism which is evident from the weakening of Nd-Mn interaction below TN, and resulting in antiferromagnetic coupling of Mn3+ ions along x-axis with Mn3+ moments oriented parallel or antiparallel to the x-component of Nd3+ moments.
