Structural, magnetic and elastic properties on stoichometric $Ni-Mn-Cu$ Heusler alloys

Heusler alloys with $Ni-Mn-Cu$ (all d-transition metal) composition have been studied; equilibrium structures for different magnetic configurations are found. Elastic constants and tetragonal distortion are analyzed. Distortion effect on densities of electronic state peaks are characterized. For this ternary family of alloys, we find that the one with the most interesting properties and mechanical stability is $Ni_2MnCu$.

Half-metallicity in $Ni_2XMn$ Heusler alloys ($X=Fe,Co,Cr$): ab-initio calculations

Lattice parameter, bulk modulus, formation energy and magnetism equilibrium structure in all-d transition metals $Ni_2XMn$ (X=Co,Cr,Fe) for Full and Inverse Heusler structure are studied by first-principles calculations. Tetragonal distortion is calculated for the equilibrium volume of each alloy and possible new equilibrium structures are reported. Density of electronic states are analyzed and the results lead to half-metallicity for this type of alloys.
