Abstract

The effect of green and ultraviolet laser light on Ba $_{0.8}$ Sr $_{0.2}$ TiO $_3$ /LaMnO $_3$ heterostructure electrical resistance was studied. In 80-200 K range illumination induces transient resistance component at ~15% of the steady-state value, the time constant associated with the transient component is ~12 s. The negative photoresistance effect is found under green, infrared and ultraviolet illumination.
