Abstract

study, the effects of Nd doping on the structural and magnetic properties of La1-xNdxBa0.2MnO3 (x= 0, 0.1, 0.2) compounds synthesized by the sol-gel method were investigated. The structural characterization was performed using X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) techniques. XRD analysis confirmed the formation of a single-phase perovskite structure with a rhombohedral structure (R-3cH space group) at room temperature for all samples. SEM images revealed homogeneous grain distributions, while XPS measurements provided insight into the valence states of La, Ba, Nd, Mn, and O elements. Magnetic properties were investigated using magnetization versus temperature (M-T) measurements under an applied magnetic field of 5 mT, as well as magnetization versus magnetic field (M-H) loops at 10 K. The results showed that Nd doping leads to a decrease in the Curie temperature and modifies the magnetic behavior of the samples, which is attributed to lattice distortions and the contribution of Nd³⁺ magnetic moments.
