Abstract

Superconductivity in high temperature superconductors is achieved by introducing charge carriers into cuprate insulators containing CuO $_{2}$ planes. Perturbation in these CuO $_{2}$ planes suppresses superconductivity by strongly affecting the electronic environment. Here we have use photoinduced electronic modification of Cu ion in CuO $_{2}$ plane to investigate the effect of local perturbation in Bi $_{2}$ Sr $_{2}$ Ca $_{2}$ Cu $_{3}$ O $_{10 + δ}$ . This method has been used to suppress superconducting transition temperature T $_{c}$ . We show that our results on photoinduced suppression of superconductivity are consistent with a scenario based on pinning of fluctuating stripes in Bi $_{2}$ Sr $_{2}$ Ca $_{2}$ Cu $_{3}$ O $_{10 + δ}$ .
