All components of the Hall effect and the magnetoresistance were measured in magnetic fields up to 160 kG at temperatures between 150 and 350 °K. The experimental results are interpreted by a six‐ellipsoid model for the valence band maxima. The ellipsoids are centered on the mirror planes of the reciprocal lattice. It is assumed that the collision time depends on energy only and that scattering takes place mainly on acoustical phonons. Only four of the twelve measured values are used to determine free parameters, the others to test the model. The hole mobilities perpendicular to the direction of the c ‐axis and parallel to it are at 200 °K μ⟂ = 926 cm 2 V −1 s −1 and μ⟂ = 1755 cm 2 V −1 s −1 . Results in the intrinsic range are reported.
