First-principles study of Zn-doping effects on phase stability and magnetic anisotropy of Ni-Mn-Ga alloys

Original language description

The effect of Zn doping on Ni-Mn-Ga magnetic shape memory alloy was studied by the firstprinciples calculations using exact muffin-tin orbital method in combination with the coherentpotential approximation and projector augmented-wave method. Trends in martensitic transformation temperature TMand Curie temperature TC were predicted from calculated energy differences between austenite and nonmodulated martensite,ΔEA−NM, and energy differences between paramagnetic and ferromagnetic state,ΔEPM−FM. Doping upon the Ga-sublattice results in stabilization of martensitic phase which indicates the increase in TM. TC is affected only weakly or slightly decreases, becauseΔEPM−FM of martensite does not change significantly with doping. The substitution ofMnatoms by Zn causes the decrease in both TMand TC. Comparing to Cu-doped Ni-Mn-Ga alloys, we predict that doping with Zn results in smaller decrease in TC but also in smaller increase in TM.
