Abstract
On the basis of the itinerant-electron model for the 4 f electrons, the energy band structure, especially the Fermi surface, is calculated for the paramagnetic heavy-electron compound CeRh 2 , which has the low-temperature electronic specific heat coefficient of 20 mJ/K 2 mol and the Kondo temperature of 400 K, by a self-consistent symmetrized relativistic APW method with the exchange and correlation potential in a local-density approximation. The Fermi surface consists of two hole spheres and a hollow electron sphere with small windows, all of which are centered at the Γ point in the Brillouin zone. The spherical property of the Fermi surface explains qualitatively well the behavior of the de Haas-van Alphen frequency branches measured recently by Sugawara et al . Candidates for the frequency branches missing in the experiment are suggested.Keywords
