Low-Field de Haas—van Alphen Study of the Fermi Surface of Aluminum

Abstract

The third-zone Fermi surface of aluminum has been studied using the low-field de Haas—van Alphen effect. The observed de Haas—van Alphen periods have been assigned to the principal portions of the third-zone surface according to the model proposed by Ashcroft. Several cyclotron masses have been determined and are found to be consistent with cyclotron resonance results, where comparison is possible. de Haas—van Alphen cyclotron masses have been compared with the band-structure masses calculated by Ashcroft. This comparison indicates that, within the uncertainties in observed and calculated masses, there is a 30 to 50% enhancement of the band-structure masses over the third-zone surface, in agreement with the calculations of Ashcroft and Wilkins.
