Abstract
Using density functional theory (DFT) with the generalized gradient approximation (GGA), we have performed a comprehensive investigation of the structural, elastic, electronic, and magnetic properties of CsMgO 3 perovskite. Our calculations reveal a ferromagnetic ground state with a lattice constant of 8.17 Bohr, this ferromagnetic configuration is confirmed to be dynamically and mechanically stable. Electronic band structure and density of states (DOS) analysis unveil half-metallic behaviour in CsMgO 3 , with a significant band gap of 6.85 eV in the spin-up direction. The calculated total magnetic moment of 3 mu B further supports its half-metallic character. The spin-polarization of p electrons in O atoms emerges as the primary source of magnetic moment. This study provides valuable insights into CsMgO 3 properties and paves the way for potential applications in spintronics or related fields due to its half-metallic character and sizable band gap.
