Figure 5
Plane-resolved valence for thicknesses of 1–8 u.c. as determined from theoretical calculations (open points) and by fitting the data (solid points, discussed in §3). For example, the square points refer to the valence of a monolayer film. The round points were calculated for a two unit-cell film, where the higher valence is the calculated surface Mn valence. The horizontal dotted line indicates the expected bulk Mn valence of 3.3. |
