Half-metallicity and magnetism of Ti2Ni1−xCoAl1−y

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

“…70,71 Zhou et al found that the substitution of Al by Si in Ti 2 NiAl Heusler alloy destroyed its HM characteristics. 86 However, the present results clearly show that the Mn 2.25 -Co 0.75 Al 1Àx Ge x (x ¼ 0, 0.25, 0.50, 0.75 and 1.00) alloys are new ferrimagnetic HM or SGS materials with 100% spin polarization, which is stable against the stoichiometric defects. The robust complete spin-polarization of Mn 2.25 Co 0.75 Al 1Àx Ge x alloys makes them series promising candidates for the practical applications in spintronics devices.…”
