Electronic structure and transport properties of UFe2 system

The electronic structure of the UFe2 compound was studied by X-ray photoemi ssion spectroscopy and (rb initio self-consistent tight binding muffin tin orbital method. This compound crystallizes in a cubic Laves phase. The calc ulated valence band spectrum is characterized by two peaks due to U(5f) and Fe(3d) states. We have found a good agreement between the experimental val ence band spectrum and theoretical ab initio calculations. The carrier conc entration estimated from the Hall effect amounts to approximate to 10(22) c m(-3).
