de Hass--van Alphen effect and the Fermi surface of the intermetallic compound AuPb$sub 2$
The de Haas--van Alphen effect has been measured in the intermetallic compound AuPb/sub 2/ (body-centered tetragonal structure) by the modulation method in fields up to 100 kG. Thirtytwo 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. lt 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. (auth)
