We have reported the synthesis, structural and magnetic properties of LaAlxMn1−xO3 (x= 0.05, 0.15, 0.25) in this article. We have synthesized these compounds through the Sol-gel citrate method and performed the Rietveld refinement of X-ray diffraction data to determine the lattice parameters. The surface elemental composition and oxidation states of LaAl0.25Mn0.75O3 are investigated using X-ray photoelectron spectroscopy (XPS) in a wide energy window of 0-1200 eV. The magnetic study shows the ferromagnetic transition of these materials. To understand the nature of magnetization from the experiments, we have studied the first principle density functional theory (DFT) and Monte-Carlo simulation. From the DFT calculations, we have confirmed the ferromagnetic structure in the ground state and studied the electronic structure of these materials. The Monte Carlo simulation has been done through the anisotropic Ising model to analyze the origin of magnetic phase transition. We have determined the anisotropy and the interaction constants from the DFT calculations. The double exchange interaction is mainly responsible for the ferromagnetic ground state.

“…The study of magnetic materials having boosted magnetocaloric effect (MCE) and large refrigerant capacity applied in low-and room-temperature magnetocaloric refrigerators is one of the current research projects recommended by the low energy consumption and the safe environmental impact of these materials [1][2][3][4][5]. The MCE is observed when magnetic systems are subjected to an external magnetic field.…”

Intermetallic Gd3Ni2 and Gd3CoNi undergo second-order ferromagnetic paramagnetic phase transition at the Curie temperature, TC. They exhibit a large magnetocaloric effect (MCE). This MCE is manifested with a high entropic peak of 8 and 8.3 J.Kg−1 K−1, at the vicinity TC under 5 T magnetic applied field for Gd3Ni2 and Gd3CoNi, respectively. With their boosted MCE and large refrigerant capacity, Gd3Ni2 and Gd3CoNi compounds can be a candidate as a magnetocaloric refrigerator which is still one of the current research projects recommended by the low energy consumption and low environmental impact of these devices. Based on the Landau theory, Gibb’s free energy leads to determine temperature-dependent parameters which correspond to the electron condensation energy and magnetoelastic coupling and the magnetic entropy change which is a very crucial parameter to evaluate the MCE of a given magnetic system.
