Detailed magnetic properties of Pr_1–𝑥Nd_𝑥MnO₃ (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. Pr_0.3Nd_0.7MnO₃) 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

This paper reports the temperature- and field-dependent magnetic properties of monovalent-doped polycrystalline sample Gd$_{0.85}$Li$_{0.15}$MnO$_3$ (GLMO) prepared by conventional solid-state reaction route. Final sintering at 1673 K for 18 h yields in the formation of well-grown, impurity phase free, single-phased, orthorhombic structured (with Pbnm space group) crystal. The optical properties have been investigated by UV-absorption spectra. The room temperature UV-absorption spectrum using Tauc’s formula gives an optical band gap of $\sim$3.12 eV. The paramagnetic (PM) state to incommensurateantiferromagnetic (ICAFM) state transition temperature increases due to Li doping. Magnetic hysteresis curve at 5 K signifies the Gd spin ordering.
