AB  - In recent years, layer-by-layer heteroepitaxy has become a versatile tool for depositing novel materials notaccessible in bulk form. While it is possible to control the mono layer sequence on an atomic scale with the helpof sophisticated analysis techniques, not all important features of the thin film growth are detectable. We reporton a detailed analysis of layer-by-layer deposited Mn-enriched La$_{2/3}$Sr$_{1/3}$MnO$_3$ thin films using various, complementary experimental techniques. Our results show that, contrary to the expectations from the growth parameters and initial characterization, the films did not grow as atomic planes but segregated into layers ofLa$_{2/3}$Sr$_{1/3}$MnO$_{3}$ with additional embedded precipitant crystals. We attribute this separation to a Volmer-Weberisland-like growth of Mn$_3$O$_4$ crystals within layers of La$_{2/3}$Sr$_{1/3}$MnO$_3$ due to increased surface tension inhibiting La and Sr oxides from sticking to nucleated Mn3O4 surfaces during the growth at high temperatures.
