The effect of sub-surface strontium depletion on oxygen diffusion in La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3−δ

The immediate surface and sub-surface composition of heat treated La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3−δ samples was measured by ion beam analysis and compared to oxygen transport properties over the same depth scale. Consistent with the literature, strontium segregation was observed for samples that rec...
