Аннотация
The Hall emf of a bismuth sample with a nonuniform current density distribution is measured under the conditions of acousto-electronic nonlinearity. The magnetic field range was 20–140 kOe at T = 4.2 K. The experimental results are explained by the contribution of drag effects and of phonon–phonon interaction to the quantity being measured.
