摘要：

The magnetocaloric, structural, electronic, magnetic and magnetocaloric properties of TbGdO3 are investigated using GGA-PBE approximation. The TbGdO3 compound has a metallic character and ferrimagnetic behavior. The magnetic properties have been found for different magnetic fields using Monte Carlo simulation. The maximum of magnetic entropy changes is 15.73 J kg- 1 K- 1 for H = 4T. Terbium gadolinium oxide exhibit significant magnetic entropy changes induced by low magnetic field variations at room temperature, making them highly suitable for active magnetic refrigerant (AMR) material and spintronic applications in household settings.
