de Haas-van Alphen Effect in AuGa2

Abstract
New de Haas-van Alphen data on the metallic fluorite compounds AuGa2 and AuIn2 are presented. Several new frequency branches have been observed, including two in AuGa2, which are tentatively ascribed to electrons in the fifth zone. The results are in general agreement with recent theoretical calculations by Switendick, which predict that the second zone is full in AuGa2.
