Magnetic Breakdown Effects in Helicon Propagation in White Tin

Abstract
The propagation of helicon waves through white tin has been studied at low temperatures and related to topological properties of the Fermi surface. The large-amplitude quantum oscillations observed at 1.2°K as the field was varied arise from magnetic breakdown. They provide a sensitive means of investigating some features of the Fermi surface. Comparisons are made with the results of a recent band-structure calculation by Weisz.
