Electronic Structure and Transport Properties of UFe2System

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