RIGID BAND BEHAVIOUR IN DILUTE ALUMINIUM ALLOYS,

Abstract

The De Haas-Van Alphen effect in Al based alloys were studied. Measurements on dilute alloys of Zn and Si in Al are reported. The results are discussed in terms of the 3rd zone Fermi surface of Al proposed by Ashcroft and the rigid band theory of alloys with which they show generally good agreement. In contrast to these results, recent measurements of the steady magnetic susceptibility and low temperature specific heat of more concentrated Al alloys by Blythe et al. have shown major departures from the predictions of the rigid band model. Attention is drawn to this striking difference without proposing a solution.
