“…Thus, at low temperatures, a perfect half-metallic ferromagnetic nature is expected for CoRuFeSi (up to 50 K). An indirect evidence of the half-metallic nature was also seen for CoRuFeGe at low temperatures [11]. In the high temperature region, the fitting of the resistivity curves indicates the absence of half-metallic nature [11].…”

“…was obtained at 300 K by them for CoRuFeSi. Bainsla et al [11], investigated the magnetic properties of the CoRuFeZ (Z = Si and Ge) alloys by studying the isothermal magnetization curves at different temperatures CoRuFeGe respectively, in which the former is found to be the highest among all the known equiatomic quaternary Heusler alloys [7][8][9][10][11]45,46,52,63]. The relatively high value of TC in these alloys gives a possibility of retaining high spin polarization at elevated temperatures.…”

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.

Despite immense interest for years in Heusler alloys as magnetoelastic materials, their application in heterogeneous catalysis has only recently been explored. We report the development of highly active, robust and magnetically separable Ni2MnAl Heusler alloy nanoparticles as a heterogeneous catalyst for hydrogenation of aliphatic and aromatic nitro compounds to the corresponding amines. The easily synthesizable Ni2MnAl nanoparticles are thermally and chemically robust and exhibited excellent chemoselectivity in the hydrogenation of a range of aliphatic and aromatic nitroarenes, including those bearing functional groups sensitive to reduction, such as alkene, bromo, iodo, carbonyl and cyano, yielding the respective functionalized amines in good yields. Moreover, this solid catalyst is magnetically separable from the reaction mixture and could be recycled and reused at least 10 times without any loss in catalytic activity. The mechanism of the Ni2MnAl Heusler alloy nanoparticles catalyzed nitro reduction was studied by various spectroscopy and control experiments and kinetics. Our work opens a new avenue of developing heterogeneous earth‐abundant metal catalysis for economic and environment‐friendly synthesis of fine chemicals owing to their straightforward synthesis and tunable composition from base‐metals and their diverse structure and properties with their high surface area, thermal and chemical stability, excellent chemoselectivity, magnetic separability and recyclability.
