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

Abstract

Monocrystals of the tetragonal compound UCoGa5 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. © 2004 Elsevier B.V. All rights reserved.
