“…Much recently, manganese-based antiperovskite structural compounds AXMn 3 (A ¼Ga, Al, Zn; X¼C, N, B) have attracted considerable attention owing to their interesting physical properties for applications and theoretical studies [1][2][3][4][5][6][7]. For example, the giant magnetoresistance (GMR) [1,2], magnetocaloric effect (MCE) [3] and giant negative thermal expansion (NTE) [4,5].…”
