Pressure dependence of Curie temperature and resistivity in complex Heusler alloys
Original language description
Using first-principles electronic structure calculations,we have studied the dependence of the Curie temperature on external hydrostatic pressure for random Ni2MnSn Heusler alloys doped with Cu and Pd atoms, over the entire range of dopant concentrations. The Curie temperatures are calculated by applying random-phase approximation to the Heisenberg Hamiltonian whose parameters are determined using the linear response and multiple scattering methods, based on density-functional theory. In (Ni1MINUS SIGNx,Pdx )2MnSn alloys, the Curie temperature is found to increase with applied pressure over the whole concentration range. The crossover from the increase to the decrease of the Curie temperature with pressure takes place for Cu concentrations larger thanabout 70% in (Ni1MINUS SIGN x,Cux )2MnSn Heusler alloys. The results for the reference Ni2MnSn Heusler alloy agree well with a previous theoretical study of E. Sasioglu, L. M. Sandratskii, and P. Bruno, Phys. Rev. B 71, 214412 (2005) and
