StEM trat dem Institut bei
Das Stuttgarter Zentrum für Elektronenmikroskopie (StEM) des Max-Planck-Instituts für Intelligente Systeme (MPI-IS) trat am 1. April 2015 unserem Institut bei. Der Transfer des von Prof. Dr. Peter van Aken geleiteten Zentrums resultierte aus der wissenschaftlichen Neuausrichtung des MPI-IS und stärkt unsere analytischen Möglichkeiten. Wir freuten uns, unsere neuen Kolleginnen und Kollegen am 1. April 2015 mit einer kleinen Veranstaltung im Auditorium zu begrüßen zu können.



StEM has joined FKF
On April 1, 2015 the Stuttgart Center for Electron Microscopy (StEM) of the Max Planck Institute for Intelligent Systems (MPI-IS) has joined our Institute, MPI-FKF. The transfer of the Center, led by Prof. Dr. Peter van Aken, is an outcome of of the scientific evolution of MPI-IS and further strengthens our analytical capabilities. To celebrate the merger, a welcome event was held in the auditorium on April 1.
Research Topic

We studied of ZrO2–La2/3Sr1/3MnO3 pillar–matrix thin films which were found to show anomalous magnetic and electron transport properties. With the application of an aberration-corrected transmission electron microscope, interfacial chemistry, and atomic-arrangement of the system, especially of the pillar–matrix interface were revealed at atomic resolution. Minor amounts of Zr were found to occupy Mn positions within the matrix. The Zr concentration reaches a minimum near the pillar–matrix interface accompanied by oxygen vacancies. La and Mn diffusion into the pillar was revealed at atomic resolution and a concomitant change of the Mn valence state was observed.
