Abstract
The Cu-local environment of the high-Tc superconductor YBa2Cu3O7−x has been investigated in the bulk form by the electron-spin-resonance technique. Two nonequivalent Cu2+ ion sites are singled out in this orthorhombic superconducting phase all over the experimental temperature range (77–298 K). The density of the magnetic moments drops under temperature increase from liquid nitrogen up to the superconductive transition temperature, therein it tails off almost linearly.
