Abstract
Oxyanion substitutions at the copper sites can stabilize the Pa free p hase YSr2Cu3O7 and allow synthesis to occur under ambient conditions ( P.R. Slater and C. Greaves, 1991; P.R. Slater et al., 1993). Here we r eport in situ Fe-57 Mossbauer spectroscopy experiments done in Y-Sr-Cu -O related oxides containing sulphate (SO42-), phosphate (PO43-) and b erate (BO33-), in the temperature range 300 K less than or equal to T less than or equal to 723 K. From the results obtained it has been pos sible to study the kinetics of oxygen loss, as well as the temperature dependence of the Fe species.
