Cyclotron effective masses and fermi velocities for the ellipsoidal hole surfaces in molybdenum

We report on measurements of cyclotron effective masses and the dimensions k_a, k_b, and k_c for the hole ellipsoid, centered at the symmetry point N, of the Molybdenum Fermi-surface. Further, assuming parabolic band-structure, the Fermi-velocities for the holes are calculated for several crystallographic directions. The experimental measurements were performed both in a conventional reflection type experiment, and in a transmission type experiment, the latter being a new technique for observation of cyclotron resonance.
