Abstract
Doping evolution of the Fermi surface topology of is studied systematically. Both local density approximation (LDA) and local spin density approximation (LSDA) predict a large Fermi surface as well as small hole pockets for doping levels . In contrast, the hole pockets are completely absent for all doping levels within . More importantly, we find no violation of Luttinger's rule in this system. The measured Fermi surface of can be explained by its half-metallic behavior and agrees with our calculations.
