Abstract

A study is performed of the effect irradiation with a series of ultrafast laser pulses at wavelengths of 514 and 257 nm has on the electrical resistivity of Ba_0.8Sr_0.2TiO₃/LaMnO₃ heterostructures. In the range of temperatures between 80 and 200 K, irradiation results in a reversible increase in the resistivity of the structure. The characteristic time of resistivity variation is about 10 s.
