In the context of this research endeavor, our primary objective is to assess the magnetic and magnetocaloric properties (referred to as MCE) of a perovskite material that has been enriched with lead (Pb), contrasting these properties with those of the pristine, undoped perovskite variant. Our inquiry is driven by the aim of exploring the viability of utilizing this material in the field of magnetic refrigeration technology, which is a greener alternative to traditional Gas-compression refrigeration systems. The materials were prepared by flash combustion, a technique known for its rapid and controlled synthesis. The samples were then subjected to X-ray diffraction (XRD) and magnetic analysis. Important information about the crystal structure, the phase composition, and the lattice parameters of the material was provided by the XRD analysis. As a result of Pb doping, we observed a slight change in the lattice properties in our experiment, which reduced the volume of the unit cell. However, neither the existence of secondary phases nor changes in the crystal structure were found. The magnetic properties of the material were analyzed using a superconducting quantum interference device (SQUID) magnetometer. Several aspects are discussed, including Curie temperatures, the nature of phase transitions and their orders, changes in magnetic entropy, and magnetocaloric properties.
