Magnetic susceptibility, transport properties, XPS and electronic structure of UCoGa5

Abstract Monocrystals of the tetragonal compound UCoGa 5 were grown. Magnetic susceptibility, electrical resistivity and thermoelectric power were measured both along the tetragonal c -axis and in the perpendicular direction. The electronic band structure was calculated by the tight-binding linear muffin-tin orbitals method in the atomic sphere approximation, with spin–orbit interactions taken into account. The X-ray photoemission spectrum was measured and calculated with a satisfactory agreement.
