Electronic Structure and Transport Properties of UFe$\text{}_{2}$ System

The electronic structure of the UFe$\text{}_{2}$ 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(5f) 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$\text{}^{22}$ cm$\text{}^{-3}$.
