“…In order to derive a SC material with a similar lattice it is enough to substitute one Co atom with V. It can be synthesized, for example, by a 50-50 mixing of Mn 2 VAl [27] and Co 2 VAl [28]. The resulting CoMnVAl (SC) compound with 24 valence electrons is nonmagnetic in agreement with the Slater-Pauling rule [29]. The unit cells and corresponding calculated bulk band structures of both Co 2 MnAl and CoMnVAl are shown in Fig.…”

We present a rational design scheme intended to provide stable high spin polarization at the interfaces of the magnetoresistive junctions by fulfilling the criteria of structural and chemical compatibilities at the interface. This can be realized by joining the semiconducting and half-metallic Heusler materials with similar structures. The present first-principles calculations verify that the interface remains half-metallic if the nearest interface layers effectively form a stable Heusler material with the properties intermediately between the surrounding bulk parts. This leads to a simple rule for selecting the proper combinations.

Half-metallic ferromagnetic (HMF) materials show high spin polarization and are therefore interesting to researchers due to their possible applications in spintronic devices. In these materials, while one spin sub band has a finite density of states at the Fermi level, the other sub band has a gap. Because of their high Curie temperature (TC) and tunable electronic been reported in a few systems, which are also discussed in this review. Thus, this review presents a consolidated picture of the magnetic and spintronic properties of this important, but relatively new class of Heusler alloys. It is expected that this will stimulate further interest in these alloys, thereby paving the way for the identification of more HMF and SGS materials. As a result of this, it is expected that more efficient spintronic devices using these alloys would emerge in the near future.

“…To the best of our knowledge, equiatomic quaternary Heusler alloys (with 1:1:1:1 stoichiometry) is explored only very little, but some of these alloys are found to show interesting properties such as high spin polarization and spin gapless semiconductor behavior. 4, [13][14][15][16] The electrical resistivity in equiatomic quaternary…”
