Abstract
We have observed a magnetic field dependent relaxation time in p-InSb at low temperatures (~lOK) where the electrical conduction is by free holes in the valence band. The relaxation peak is only observed in nondegenerate specimens for those acoustic modes which are piezoelectrically active. The results are compared with the acousto-electric theory of Hutson and White and found to be in substantial agreement.
