Research Subjects

  • Magnetic and electronic properties of perovskites studied with NMR, Mossbauer Effect and
    synchrotron radiation based X-ray spectroscopy techniques : XAFS, XMCD, XES, RIXS.
    Materials studied: “colossal magnetoresistive” manganites, double perovskites, Ruthenium-hybrid cuprates Problems: charge- and spin dynamics, electronic and magnetic phase segregation, spin- and orbital moments of individual elements, influence of hydrostatic pressure and relation to the bulk magnetic and electronic transport properties of bulk samples and thin films.
  • Individual site magnetic properties of expanded lattice intermetallics: RE - 3d compounds
    containing light interstitial elements H, N, C.
    Materials studied: RE2Fe17(N,C,H)x and RE2Fe14BHx permanent magnet materials,
    REFe2Hx and REMn2Hx compounds Problems: individual site electronic and magnetic properties: magnetic moments and their coupling, individual site contributions to the magnetocrystalline anisotropy, impact of light interstitial atoms on these properties, influence of hydrostatic pressure and relation to the bulk magnetic and anisotropic properties.
