Abstract
The magnetic breakdown field between the second and third zones in zinc has been determined from measurements of the absolute amplitude of the de Haas-van Alphen oscillations of the needles by a torque method. By taking the measurements to lower magnetic field and by calculating the curvature of the needles we are able to determine the value of the breakdown field with much greater certainty than previously. With the external field along thec axis, the breakdown field is found to be 3.5±0.3 kG. As the external field is tipped away from thec axis, the breakdown field is found to vary with angle as though the energy gap between the zones were 6.75(1+2.28 cos ϑ) meV for ϑ from 0 to 80°. The Dingle temperature was found to be isotropic within 0.1 K.
