Band Structure Calculations for (Ni1-XCux)2MnGa Heusler Alloys
Ni2MnGa alloy exhibits significant magnetocaloric effect due to structural and magnetic transition, which take place at similar temperature range. In this report we present band structure calculations for Ni2MnGa doped with Cu performed within KKR-CPA scheme. We also calculated the estimated temperature of the magnetic transition as a function of dopant concentration within Mean-Field-Approach (MFA). Our calculations show that the Curie temperature increases with Cu doping in agreement with recent experimental data.
