Abstract :
The de Haas-van Alphen frequencies as well as the effective masses for a magnetic field parallel to the crystallographic c→ direction are calculated within the local spin density approximation for MgB2 and TaB2. In addition, we analyze the plasma frequencies computed for each Fermi surface sheet. We find a large anisotropy of Fermi velocities in MgB2 in contrast to the nearly isotropic behavior in TaB2.
