Highly spin-polarized electronic structure and magnetic properties of Mn_2.25Co_0.75Al_1−xGe_x Heusler alloys: first-principles calculations

Abstract

The complete spin polarizations of Mn2.25Co0.75Al1−xGex are proved to be robust against stoichiometric defect and lattice deformation, whose easy magnetization direction can be manipulated from in-plane direction to out-of-plane one under uniaxial strain.
