English abstract:
The many surface reconstructions of (110)-oriented lanthanum strontium manganite (La0.8Sr0.2MnO3, LSMO)
were followed as a function of the oxygen chemical potential (μO) and the surface cation composition.
Decreasing μO causes Mn to migrate across the surface, enforcing phase separation into A-site-rich areas
and a variety of composition-related, structurally diverse B-site-rich reconstructions. The composition of these
phase-separated structures was quantified with scanning tunneling microscopy, and these results were used to
build a two-dimensional phase diagram of the LSMO(110) equilibrium surface structures.
