Poster summary
- First-principles calculations and the mean field approximation were employed to study the structural, electronic and magnetic properties of the full Heusler Ga₂MnCo alloy. The structural analysis unveiled the stability of Ga₂MnCo in a ferromagnetic state. Regarding electronic and magnetic attributes, the calculations demonstrated that Ga₂MnCo exhibits a metallic nature, featuring distinct spin-up and spin-down states. Additionally, the magnetic properties and phase diagrams were computed, and the results were thoroughly examined. The system presents a rich critical behavior, including both first and second-order phase transitions.
