(a) X-ray fluorescence spectrum above and below critical angle for total reflection for 16 nm on (101) at and 150 Torr . The spectra have been normalized to the La and Mn intensity for comparison. Note the increase in the Sr intensity below and the increase in the substrate signal above . (b) Fit to TXRF ratio (left axis) as a function of incidence angle . For reference, the penetration length is plotted on the top horizontal axis. To emphasize the position of , the normalized Sr and La TXRF intensities are shown on the right axis.

(a) Sr surface region concentration vs oxygen partial pressure at . (b) Sr surface enrichment as a function inverse temperature for a variety of oxygen partial pressures. The quantity denotes the Sr/La ratio integrated over the first 2 nm, while is the bulk ratio, i.e.,. The lines are linear fits to equilibrium data taken between 500 and .
