Measurements of resistivity, Nernst, Seebeck and Hall effects of Bi 2223 epitaxial thin films for magnetic fields between 0 and 5 T and temperature range 5-300 K are reported.

We had performed a study on magnetoresistivity, Seebeck, Nernst and Hall effects in the mixed and normal state for Bi2223 thin films in magnetic fields between 0 and 5 T and in the temperature range 5-300 K. The critical temperatures, the Hall concentration, the Nernst and Seebeck coefficients depend strongly on the iron content in the samples. From our experimental data in the mixed state and fluctuation regime, the upper critical field slope (dB(c2)/dT)

The magnetic moments in Ni/Pt multilayers are thoroughly studied by combining experimental and ab initio theoretical techniques. SQUID magnetometry probes the samples' magnetizations. X-ray magnetic circular dichroism separates the contribution of Ni and Pt and provides a layer-resolved magnetic moment profile for the whole system. The results are compared to band-structure calculations. Induced Pt magnetic moments localized mostly at the interface

-ray magnetic circular dichroism measurements have been performed on Ni/Pt multilayers at a temperature of 10 K. The element specificity and shell selectivity of the technique allows us to probe Ni and Pt magnetic moments and to separate them into their constituent spin (mu (S)) and orbital (mu (L)) magnetic moments. The Ni magnetic moment at the interface is found to be reduced. However, magnetically "dead" Ni layers are unambiguously ruled out.

tate-of-the-art x-ray magnetic circular dichroism measurements of V at the L-2,L-3 edges with an excellent signal-to-noise ratio are analyzed for a Fe0.9V0.1 disordered alloy and a Fe/V-3/Fe(110) trilayer which were prepared in UHV and measured in situ on a Cu(100) single crystal. The absorption fine structure and the magnetic dichroism are discussed in detail with the help of ab initio theory. Several approaches known from literature to obtain magnetic

The effect of substitution of the anion Te by Se in non-stoichiometric Cr(5)Te(8) has been investigated with respect to its crystal structure, magnetic properties, and electronic structure. The compounds Cr((1 + x))Q(2) (Q = Te, Se; Te:Se = 7:1; (1 + x) = 1.234(6), 1.264(6), 1.300(7)) were synthesized at elevated temperatures followed by quenching the samples to room temperature. The crystal structures have been refined with X-ray powder diffraction

We report on XMCD measurements at the L2,3 edges of the early 3d transition metals, Ti, V and Cr, polarized by Fe. In contrast to the classical ferromagnets Fe, Co and Ni, the XMCD spectra reveal a complex and detailed fine structure. We analyze the experimental data with the help of full-relativistic ab initio calculations of the x-ray absorption cross section μ(E) that provide the energy-dependent XMCD spectrum and the correlated magnetic moments

The existence of flat areas of a Fermi surface (FS), predicted by electronic structure calculations and used in models of both magnetically mediated and phonon-mediated Fulde-Ferrell-Larkin-Ovchinnikov superconducting states, is reported in the paramagnetic phase of the ferromagnetic superconductor ZrZn2 using positron annihilation. The strongly mass-renormalized FS sheet, dominating the Fermi level density of states, is seen for the first time.

TlTaSe3 was prepared from a fused mixture of Tl4Ta2Se11, Ta and Se in the molar ratio 1:2:1. The compound shows dimorphism with H-TlTaSe3, hexagonal, space group P6(3)/mmc, a = 7.2436(6), c = 5.9736(6) angstrom, c/a = 1.213 and O-TITaSe3, orthorhombic, space group Pnma, a = 9.554(13), b = 3.6244(6), c = 14.7271(17) angstrom. The crystal structure of H-TlTaSe3 is isotypic to BaVSe3 whereas that of O-TlTaSe3 is closely related to the NH4CdCl3-type.

he effect of substitution of the cation Cr by Ti in Cr(5)Te(8) has been investigated with respect to its crystal structure, magnetic properties, and electronic structure. The compounds Cr(5-x)Ti(x)Te(8) (x = 0, 0.5, 1, 1.5, 1.85, 2, 3, 4, 5) were synthesized at elevated temperatures followed by slow cooling the samples to room temperature. The crystal structures have been refined with X-ray powder diffraction data with the Rietveld method. Three
