Abstract

The electrical resistance of Ba_0.8Sr_0.2TiO₃/LaMnO₃/Ba_0.8Sr_0.2TiO₃ film heterostructures has been studied. It is shown that the resistance decreases significantly with a temperature below the maximum temperature of about 170 K. Thus, for such heterostructures, the effect of quasi-two-dimensional conductivity was discovered, but only at certain layer thicknesses.
