Abstract : The de Haas-van Alphen effect has been measured in the intermetallic compound AuPb2 (body-centered tetragonal structure) by the modulation method in fields up to 100 kG. Thirty-two frequency branches have been observed in the (100), (110), and (001) planes, and several cyclotron effective masses have been determined. The nearly-free-electron model has been used to construct a Fermi surface, which explains the large frequency branches and is compatible with the high-field magnetoresistance results of Bass, Edwards, and Schroeder. It has been possible to determine the shape of some sheets by inversion of the de Haas-van Alphen data. The lattice parameters have been determined at room temperature and at liquid helium temperature. (Author)
