Abstrakt

We report on the persistent and erasable photoinduced change of normal-state transport and superconducting properties of oxygen-deficient YBa2CU3O6.6 thin films. After illumination with white light for several hours at 150 K, a decrease of the electrical resistivity, an increase of the number of mobile holes, and a change of the magnetoresistance caused by superconducting order-parameter fluctuations, were observed. From the latter measurement, we find a photoinduced enhancement of the superconducting coherence lengths in both in-plane and out-of-plane directions.
