Abstract
The authors have measured eddy-current decay times in orientated single crystals of Cd, Zn and Mg between 1.3K and 300K to obtain the residual and temperature-dependent resistivity and anisotropy. Deviations from Matthiessen's rule have been measured for Cd and Mg in order to estimate the temperature range in which one can reliably obtain values of the 'ideal' phonon resistivity and its anisotropy, to be compared with the theory of phonon-limited resistivity. The characteristic residual scattering anisotropy, which is very difficult to obtain from a conventional resistance measurement, has been determined for a dilute homovalent Cd(Zn) alloy, and the results indicate that the electron relaxation time is not isotropic for this system.
