| Zusammenfassung: | Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Atomic engineering of perovskite films and interfaces is significantly improved by in situ optimization of reflection high-energy electron diffraction (RHEED) features resulting from surface BO₆ octahedral rotations seen during molecular-beam epitaxy growth. This approach yields Sr-doped manganite films across the phase diagram with magnetotransport properties that are, for the first time, identical to bulk single crystals. Careful structural analysis of manganite/titanate interfaces shows that cation intermixing and unit cell dilations are eliminated, while BO₆ rotations and Jahn-Teller-type elongations are nearly completely suppressed at the interface |
