Abstract :
In the present paper, we consider the influence of magnetic fields B ≤ 2 T on the electric current in thin PbSnTe:In films, kept at T=4.2 K, with prevailing injection of charge carriers out of contacts and space-charge-controlled limitation of the current. Data for various orientations of the field B with respect to the direction of the current in the film plane, and also data on transient currents, are reported. The data obtained are analyzed within the theory of space-charge-limited electric currents and with due regard for ferroelectric properties of PbSnTe:In.
