ABSTRACT Heusler alloys containing Co and Mn are amongst the most heavily studied half-metallic ferromagnets for future applications in spintronics. Using state-of-the-art electronic structure calculations, we investigate the effect of doping and disorder on their electronic and magnetic properties. Small degrees of doping by substituting Fe or Cr for Mn scarcely affect the half-metallicity. A similar effect is also achieved by mixing the sublattices occupied by the Mn and sp atoms. Thus the half-metallicity is a robust property of these alloys.

    ABSTRACT: We expand our study of the full-Heusler compounds [I. Galanakis , Appl. Phys. Lett. 89, 042502 (2006)] to cover also the case of doping and disorder in the case of Co2MnAl and Co2MnGa half-metallic Heusler alloys. These alloys present a region of very small minority density of states instead of a real gap. Electronic structure calculations reveal that doping with Fe and Cr in the case of Co2MnAl retains half-metallicity contrary to the Co2MnGa compound. Cr impurities present an unusual behavior, and the spin moment of the Cr impurity scales almost linearly with the concentration of Cr atoms contrary to Co(2)MnZ (Z=Si,Ge,Sn) where it was almost constant. Half-metallicity is no longer preserved for both Co2MnAl and Co2MnGa alloys when disorder occurs and there is an excess of either Mn or sp atoms.

    ABSTRACT: X-ray absorption (XAS) and x-ray magnetic circular dichroism (XMCD) techniques are utilized to explore the ferromagnetic/barrier interface in Co2MnSi full Heusler alloy magnetic tunnel junctions. Structural and magnetic properties of the interface region are studied as a function of the degree of site disorder in the alloy and for different degrees of barrier oxidation. Photoelectron scattering features that depend upon the degree of L21 ordering are observed in the XAS spectra. Additionally, the moments per 3d hole for Co and Mn atoms are found to be a sensitive function of both the degree of L21 ordering and the barrier oxidation state. Significantly, a multiplet structure is observed in the XMCD spectra that indicates a degree of localization of the moments and may result from the half-metallic ferromagnetism (HMF) in the alloy. The magnitude of this multiplet structure appears to vary with preparation conditions and could be utilized to ascertain the role of the constituent atoms in producing the HMF, and to examine methods for preserving the half-metallic state after barrier preparation. The changes in the magnetic structure caused by barrier oxidation could be reversed by inserting a thin Mg interface layer in order to suppress the oxidation of Mn in the Co2MnSi layer.

    ABSTRACT: The influence of the growth temperature on the atomic ordering and interlayer diffusion of Heusler alloy Co2FeSi films grown on GaAs(001) substrates has been studied using high-resolution transmission electron microscopy. The Co2FeSi/GaAs(001) films grown below 200 °C show a coexistence of the Heusler-type L21 phase and the disordered B2 phase, which can be seen mainly near the interface, due to the low growth temperature. This phase coexistence can affect the spin polarization of the Co2FeSi layer near the interface. On the other hand, the film grown at an elevated temperature of 300 °C shows a uniformly atomically ordered L21 phase, indicating that 300 °C is approximately the transition temperature to the atomically ordered L21 structure. The elevation of the growth temperature, however, results in the formations of interfacial compounds above 250 °C, which could be detrimental to the efficient electrical spin injection.
