Abstract

The superconducting ceramic samples in Y–Ba–Cu–O system with various content of fluorine are synthesized. It is found, that even slight doping of YBa₂Cu₃O_yF_x by fluorine (x=0.05) shifts of the superconducting transition towards high temperatures by 10–12 K. The obtained data are interpreted suggesting the generation of acceptor levels in a forbidden band and presence of holes in YBa₂Cu₃O_y when doping by fluorine, that enhances the temperature of charge carrier «pairing».
