Abstract

During the usual thermal treatment of the superconducting YBa2Cu3O7 compound, cobalt and iron substitute predominantly at the Cu(1) site as shown by neutron and X-ray diffraction. EXAFS, and IR studies. A sequence of thermal treatments permits reversible cycling of cobalt-57 between the two copper sites. This allows us to micro-probe both the chain and the sheet site with varying degree of oxygen content.
