The Electronic Structure and the Fermi Surface of α-Cerium

抄録

On the basis of the itinerant 4f electron model, the electronic structure is calculated for α-Ce by a relativistic linear augmented-plane-wave method. The Fermi surface is found to consist of small electron and hole pockets as well as the multiply-connected hole sheet. The multiply-connected hole sheet holds no open orbit, and this result is not inconsistent with the recent experimental result for the high-field magnetoresistance.
