“…As one promising FIM, binary Heusler compound Mn 3 Ga has drawn considerable interest due to its exceptional properties such as large PMA, high Curie temperature exceeding 730 K, and a low Gilbert damping constant [10][11][12][13][14][15][16][17][18][19]. The Mn 3 Ga alloy exhibits diverse phases, among which are the metastable D0 3 phase characterized by a cubic Heusler-type structure, and the tetragonal D0 22 phase [10,14].…”

Mn3Ga-based ferrimagnets have emerged as a promising platform for energy-efficient spintronics. However, the challenge of identifying an appropriate substrate with minimal lattice misfit for the growth of high-quality Mn3Ga films persists. Here we investigate the interfacial energetic stability and magnetic anisotropy at the Mn3Ga/GaAs interface through first-principles electronic structure calculations. Four types of interface models based on different configurations, including MnMn/As, MnMn/Ga, MnGa/As, and MnGa/Ga, are systematically examined. Our findings reveal that the MnGa/Ga interface exhibits the largest perpendicular magnetic anisotropy but is energetically the least favorable. Conversely, the MnMn/As interface is energetically the most favorable but demonstrates a lower interfacial perpendicular magnetic anisotropy. Importantly, our calculations align well with the experimentally observed formation of the secondary phase Mn2As. This study deepens our understanding of the interfacial properties in Mn3Ga/GaAs and offers some insights into their optimization through strategic interfacial engineering.
