This paper presents our study on the production of a sample system of perovskite manganites REMnO3 with rare earth ions RE=La,Nd,Pr respectively by means of a solid-state reaction technology. The structure and magnetic properties have been investigated. The crystal structure of LaMnO3 is cubic, whereas the crystal structures of NdMnO3 and PrMnO3 are orthorhombic. We have investigated the dependence of the magnetic temperature on the samples’ temperature and the magnetic field. In addition, we have calculated the Curie and Weiss temperature as well as Curie constants of the samples. We have discovered other transition at 15.3 K and 42.5 K for the NdMnO3 sample. We have compared the magnetic properties of the samples, thereby discussing the impact of rare earth ions on the properties of the sample systems.
