Description
Oxyanion substitutions at the copper sites can stabilize the Ba free phase YSr2Cu3O7 and allow synthesis to occur under ambient conditions. Here we report in situ 57Fe Moessbauer spectroscopy experiments done in Y-Sr-Cu-O related oxides containing sulphate (SO42-), phosphate (PO43-) and borate (BO33-), in the temperature range 300 K≤T≤723 K. From the results obtained it has been possible to study the kinetics of oxygen loss, as well as the temperature dependence of the Fe species. (orig.)
