Abstract
- We investigate the effect of the electronic and magnetic properties on nonmagnetic Cu-3d atoms doping the Heusler alloy Ti<subscript>2</subscript>Ni<subscript>1-x</subscript>Cu<subscript>x</subscript>Al (0 ≤ x ≤ 1) using first-principles calculations. The optimized lattice constants are consistent with the Vegard law, and energies of doped systems become more lower as the increase of x concentration. A critical transition diagram from half-metallic to metallic characters is discussed. In addition, the magnetic interactions between p and d states are illustrated. Finally, magnetic moments are given as a function of x value, which implies that the Slater-Pauling rule is obeyed at low Cu content (x ≤ 0:2). [ABSTRACT FROM AUTHOR]
