    Notes: Density functional calculations are used to elucidate the electronic and magnetic structure of SrRuO3. Itinerant ferromagnetic behavior is found both in the cubic perovskite and the actual orthorhombic structure. The calculated moment is 1.59 μB. Unusually strong hybridization is evident in both the electronic structure and magnetism. The Fermi velocities indicate significant spin differentiation of the transport properties.

    Calculated spacer-layer Friedel oscillations in Co/Cu(001) : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: The induced complete position-dependent magnetization density of the copper spacer layer is calculated for Co/Cu(001), as modeled by a Co/Cu9/Co slab. This density is then analyzed in terms of Friedel oscillations. It is found that the variation of the density is well described by two periods, 1.2 and 1.6 monolayers, which are the nonaliased versions of the RKKY periods found in the interlayer coupling. The induced Cu magnetization is not well described in terms of local Cu moments, arising from local exchange interactions, but rather has significant free electron character, in the way that it is mainly induced by magnetic interface scattering. © 1996 American Institute of Physics.

    bcc cobalt: Metastable phase or forced structure? : 37th Annual conference on magnetism and magnetic materials (1993)

    Notes: General potential linearized augmented plane wave calculations of the elastic and magnetic properties of body-centered-cubic (bcc) Co are presented and discussed. Particular attention is given to the nature of the stability of bcc Co films that have been grown epitaxially on GaAs substrates. The bcc structural phase of Co, which is not found in nature, is calculated to be unstable with respect to a tetragonal distortion that transforms it continuously into the face-centered-cubic (fcc) phase. This means that bcc Co is not a true metastable phase of bulk Co. The thinner films of bcc Co that have been synthesized are more properly termed forced structures. We speculate that the few existing thick (up to 357 A(ring)) samples of bcc Co are stabilized by the presence of impurities or other defects. This is further supported by discrepancies between the measured and calculated magnetic moments in bcc Co.

    Local and nonlocal density functional studies of FeCr : The 6th joint magnetism and magnetic materials (MMM)-intermag conference (1994)

    Notes: Local spin density approximation and generalized gradient approximation calculations are reported for ferromagnetic B2 FeCr. Both shear elastic constants are found to be positive, indicating metastability of the B2 structure. Both the moments of the Fe and Cr layers are ferromagnetically aligned, with the Fe moment being considerably depressed. This is in contrast to the behavior for thicker films. The evolution of the behavior as a function of the layer thickness is addressed using supercell calculations. It is found that Fe monolayers in bcc Cr are ferromagnetically aligned with the neighboring Cr moments, while thicker Fe layers are antiferromagnetically aligned with the adjacent Cr layers.

    Arsenic poisoning of magnetism in bcc cobalt (1992)

    Notes: Highly converged local spin-density approximation calculations are used to determine the effectiveness of As as a poisoning agent for the magnetism of bcc Co films grown on GaAs. To do this, supercell calculations of the magnetization were performed using an extension of the general potential linearized augmented plane-wave method for Co7As, Co15As, and Co31As. The effect of the nearest-neighbor relaxation around As impurities, calculated using total energy techniques, was included. It is found that substitutional As is moderately effective as a poisoning agent, each As atom contributes a moment of −3.8μB, and this may be important in explaining the discrepancy of 0.2–0.3μB between the calculated magnetization of bcc Co and the measured magnetization of bcc Co films on GaAs.

    Magnetism and electronic structure of (La,Ba)CoO3 (abstract) : The 41st annual conference on magnetism and magnetic materials (1997)

    Notes: The (La,Ba)CoO3 perovskites have attracted recent interest because of the discovery of giant magnetoresistance in films of this material that is possibly related to the larger effects in (La,Ca)MnO3. The present density functional studies were performed to elucidate the electronic and magnetic properties of these cobaltates and in the case of LaCoO3 the relationship to the structural parameter giving the rotation of the O octahedra. Cubic perovskite BaCoO3 is found to have a ferromagnetic ground state in agreement with experiment. Although less hybridization is expected in this system relative to manganates, the moment is still reduced noticeably from Hund's rule value. In LaCoO3 a strong structural instability of the cubic perovskite structure against rotation of the octahedra is found. At least two metastable ferromagnetic states are found and these couple strongly to the distortion related to the instability.

    Band structure of Bi2Sr2CuO6: Strong effects due to structural modulation (1995)

    Notes: Abstract The electronic structure of idealized tetragonal Bi2Sr2CuO6 is compared with that of an orthorhombic √2×√2 model that includes atomic displacements due to the structural modulation. The electronic structure, particularly that related to Bi and O(3) atoms, is strongly modified near the Fermi energy. In particular the shape and topology of the Bi-O(3) related Fermi surfaces near the ¯M point are changed. With the modulation, bands occur near the Fermi energy over a significant part of the zone near this point. A method is proposed to distinguish between lattice distortions and antiferromagnetic correlations as the cause of recently observed shadow Fermi surfaces.
