## Abstract

The acoustomagnetoelectric effect (AME) in a semiconductor superlattice (SL) has been studied for an acoustic wave in the region ql >> 1. The expression for the acoustomagnetoelectric current j{sup AME} was calculated in the {tau} = constant approximation. The result indicates that the existence of j{sup AME} in SL may be due to the finite gap band and the periodicity of the electron spectrum. It is shown, in particular, that when {omega}{sub q} > {Delta} and {Delta} >> T ({omega}{sub q} is the frequency of the acoustic phonons; 2{Delta} is the miniband width of SL and T is the temperature measured in energy unit) the SL behaves as a monopolar semiconductor bulk material and in that case j{sup AME} {yields} 0.
