In this work, the RMO3 (R = Pr, Nd and M = Fe, Co) perovskites had been synthesized by hydrothermal method. The structural properties of RMO3 prepared samples were investigated by using X-ray diffraction (XRD) analysis. These prepared perovskites showed the orthorhombic structure with the Pbnm space group. The Williamson-Hall method was used for determining the size of crystallites (DW–H) and lattice strains (ε) of the samples. In addition, scanning electron microscopy (SEM) was used for investigating the morphology and for determining the sizes of RMO3 particles. For magnetic characterizations of the samples, vibrating sample magnetometer (VSM) and FC and ZFC measurements had been used. The Neel temperatures (TN) of R ions were determined at TN = 29, 8 and 9 K for PrFeO3, PrCoO3, and NdCoO3 perovskites, respectively. The spin reorientation temperature (TSR) of NdFeO3 had been displayed at T = 163 K during FC and ZFC protocols. Thereafter, the Curie–Weiss law had been used for calculating the CW temperatures (θCW) and Curie constants (C) of the all samples based on FC measurements data.
