Abstract
Experimental observations of acoustoelectric oscillations in [110] and [111] oriented InSb at 77°K in the presence of a transverse magnetic field are described. The period of the oscillations in the [110] samples, equal to the interelectrode transit time of a domain at the shear wave velocity for fields near threshold, increases two‐ or three‐fold for higher electric fields. The possible origin of this anomalous period is discussed.
