Temperature Dependence of Carrier Scattering Rate in Copper from Magnetoacoustic Experiments

Abstract

The temperature dependence of the carrier scattering rate in copper has been determined from magnetoacoustic data. For both the (100) central belly orbit and the (110) 'dogs-bone' orbit a T3 dependence is observed, the coefficients of the corresponding term in the scattering rate agreeing well with those obtained from radio frequency size-effect experiments. Previously reported discrepancies between the results obtained by the two methods are discussed and tentatively resolved.
