Electronic properties of bulk copper-aluminum and copper-zinc alloys

Magnetic-susceptibility, as well as resistivity, Hall-effect, transverse-magnetoresistance, and thermoelectric-power, measurements have been made on a series of well-characterized bulk samples covering the entire copper-aluminum and copper-zinc phase diagrams. In both systems the resistivity of the $\ensuremath{\gamma}$ phase exhibits a sharp minimum as a function of composition. This minimum correlates with anomalies observed in the other measured properties and supports the hypothesis that the behavior is due to electronic effects associated with overlap between the Fermi surface and the Jones zone for this structure. Comparison of the properties of other phases in the two systems indicates similarities which can be also ascribed to band-structure effects.
