Electronic band structures and magnetism of the cubic perovskite-type manganese compounds Mn₃MC (M=Zn,Ga,In,Sn)

Magnetism, magnetocaloric effect and positive magnetoresistance in Fe-doped antipervoskite compounds SnCMn3−xFex (x=0.05–0.20)

“…However, there are rare reports on the doped antiperovskite compounds AXMn 3 on Mn site in comparison with those on A site. Previous theoretical investigations have proved that the 3d electrons contribute mainly to the electronic band near Fermi energy [19]. Thus the substitution on Mn site by other 3d elements could modify the electronic structure near Fermi level and the properties of compound.…”

“…Obviously, this explanation is not applicable to SnCMn 3 À x Fe x since both T C and M S decrease with increase in x, but the lattice constant decreases. According to the previous theoretical studies, the density of states (DOS) at the Fermi level E F [N(E F )] is mainly contributed from Mn 3d electrons in Mn-based antiperovskite compounds [19]. Clearly, the [20,21].…”

Electronic structure and x-ray magnetic circular dichroism in the Mn3CuN perovskite

“…The energy band structure of the Mn 3 MX (M=Ga, Sn, Zn, Cu and X=C and N) systems has been calculated by various methods [24][25][26][27][28]. In the present study, we focus our attention on the theoretical investigation of the x-ray magnetic circular dichroism (XMCD) in the low temperature non-collinear phase of Mn 3 CuN.…”

Magnetic/structural phase diagram and enhanced giant magnetoresistance in Zn-doped antiperovskite compound Ga1−xZnxCMn3

“…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].…”
