This article investigates the magnetic and electronic properties of the magnesioferrite (MgFe₂O₄) mineral found in the rock formations of Uzbekistan using both experimental and computational methods. The magnetic susceptibility was measured over a high-temperature range (300–1200K) and was found to follow a linear Curie–Weiss law within two temperature intervals, with a polymorphic phase transition observed at 810K. Differential Scanning Calorimetry (DSC) results confirmed this transition, while thermogravimetric analysis showed the sample’s stability at high temperatures. The electronic structure density and band system were calculated using Density Functional Theory (DFT), revealing the semiconductor and ferrimagnetic properties of magnesioferrite. Geometry optimization results confirmed the stable configuration of the crystal lattice and convergence of the electronic system. The obtained data contribute to a deeper understanding of the thermodynamic, magnetic, and electronic properties of magnesioferrite and support its potential applications in spintronics and other modern technologies.
