We find an unexpected dependence on film thickness of the integrated magnitude of the heat-capacity anomalies as the films undergo layer-by-layer transitions. We measure the penetration depths of the ordering from the surface and next-to-surface layers which are pertinent to the highly correlated thermal behavior.[SDGs]SDG7journal article10.1103/PhysRevLett.88.0855072-s2.0-4644332241WOS:000174030000016
