Onsager Phase Factor in Cadmium

Abstract

Precise de Haas-van Alphen phase measurements for the lens orbit in Cd with the magnetic field in the basal plane show that the Onsager phase factor $\gamma$ for this orbit is $\frac{1}{2}$ and not $\frac{3}{4}$ as predicted recently by Hosack and Taylor. A spin-splitting zero is observed in the (10¯10) plane, giving a value for $g\approx 1.6$.
