    • Abstract

       

      Detailed magnetic properties of Pr1–𝑥Nd𝑥MnO3 (𝑥 = 0.3, 0.5 and 0.7) have been reported. All the samples crystallize in orthorhombic perovskite structure with Pnma space group. Magnetization measurements under field cooled (FC) protocal reveal magnetization reversal at low temperatures and low magnetic field. This indicates clear evidence of two magnetic sublattices aligned opposite to each other. There is a well-defined maximum around 48 K in the 𝑥 = 0.7 sample (i.e. Pr0.3Nd0.7MnO3) in the 𝜒' value which is identified as paramagnetic to ferrimagnetic transition. The peak value shifts to higher temperature with decrease of 𝑥 and width of the maximum broadened. It is also observable that with decrease of Nd, both the value of 𝜒' and 𝜒" decrease. An attempt is made to explain the magnetization reversal within the framework of available models
