Study of half metallicity, structural and mechanical properties in inverse Heusler alloy Mn₂ZnSi_(1−x)Ge_x and a superlattice

Abstract

The electronic and magnetic properties of Mn2ZnSi(1−x)Gex (x = 0.0, 0.125, 0.25, 0.375, 0.5, 0.625, 0.75, 0.875, and 1.0) inverse Heusler alloys and Mn2ZnSi/Mn2ZnGe superlattice have been investigated using first-principles calculations.

Effects of Interfacial Termination, Oxidation, and Film Thickness on the Magnetic Anisotropy in Mn2.25Co0.75Ga0.5Sn0.5/MgO Heterostructures

“…For example, the first reported SGS material was just obtained by substituting Co for Pd in PbPdO 2 . According to the previous studies, the doping of transition metal and s–p elements usually has a different effect on the control of the band structure. − In order to develop a new SGS material, we propose to dope transition metal and s–p elements in half-metals, nearly half-metals, or magnetic semiconductors. In fact, the band structures of half-metals, SGSs, and magnetic semiconductors are continuously transitional, as shown in Figure S1, indicating that it is highly possible to achieve one of them by doping the other one.…”

Investigation of mechanical, thermodynamical, dynamical and electronic properties of RuYAs (Y = Cr and Fe) alloys

“…Spintronic devices have many advantages, such as higher data storage capacity, lower power consumption, higher speed for data * Author to whom any correspondence should be addressed. transfer and processing over the conventional semiconducting electronic devices [4,5]. The spintronic materials have extensive applications such as spin-transfer torque, giant magnetoresistance, magnetic random access memory, and magnetic tunnel junction devices, which plays an important role in materials sciences [6].…”

Highly spin-polarized electronic structure and magnetic properties of Mn2.25Co0.75Al1−xGex Heusler alloys: first-principles calculations

“…Therefore, it is important to nd the completely spin-polarized HM and SGS which are robust against the stoichiometric defects and lattice distortion. Additionally, the substitution is an effective way to tailor the electronic structure, [58][59][60][61][62][63][64] where the rst SGS was obtained by substituting Co atom for Pd in PbPdO 2 . 21,22 Ayuela et al rstly reported that Co 2 MnGa has a large spin-up density of states (DOS) at the Fermi level, while spin-down density of states at the Fermi level nearly vanishes, which results a high spin polarization despite it's not completely spin-polarized.…”
