Abstract:
Superconductivity in high temperature superconductors is achieved by introducing charge carriers into cuprate insulators containing CuO2 planes. Perturbation in these CuO2 planes suppresses superconductivity by strongly affecting the electronic environment. Here we have use photoinduced electronic modification of Cu ion in CuO2 plane to investigate the effect of local perturbation in Bi2Sr2Ca2Cu3O10+δ. This method has been used to suppress superconducting transition temperature Tc. We show that our results on photoinduced suppression of superconductivity are consistent with a scenario based on pinning of fluctuating stripes in Bi2Sr2Ca2Cu3O10+δ.
