Abstract
Dense samples of the perovskite Sm1−xSrxCoO3 (where x=0, 0.2, 0.4, 0.5 and 0.6) have been prepared. The samples were18O/16O isotopically exchanged at a variety of temperatures between 500°C and 900°C. Subsequent analysis of the diffusion profile using Secondary Ion Mass Spectrometry (SIMS) allowed the oxygen self-diffusion coefficient, D*, and surface exchange co-efficient, k, to be determined. From the temperature dependence of these parameters the activation energies for both processes were evaluated. The surface coverage of samarium, cobalt and oxygen in SmCoO3 was determined from calibration samples using Low Energy Ion Scattering (LEIS). LEIS was used to determine the effect of strontium doping on the surface composition and the18O-concentration at the surface of a number of the18O-exchanged samples.
