报告题目:Observation and Manipulation of Electronic Phase Separation in Complex Oxides
报告摘要:
For strongly correlated systems, it has been known that co-existence of electronic phases is often energetically favored. Investigation of the so-called electronic phase separation (EPS) phenomena is not only important for understanding the strong electronic correlations in these materials, but also very useful for tuning their physical properties. In this work, we push this trend to its limit by developing the capability of manipulating EPS in colossal magnetoresistance (CMR) manganites systems. We demonstrate that it is possible to pattern the EPS in manganites and thus design the physical properties of the systems. By doing so, we are able to gain a much deeper insight of the physical origin of electronic phase separation in these materials.
报告人简介:
Jian Shen received his Ph.D from Max-Planck Institute of. Mikrostrukturphyisik in 1996, and became a joint faculty in Oak Ridge National Laboratory and The University of Tennessee in 1998. He joined Fudan university in 2010 as the HaoQing chair professor and the head of physics department, and was elected as APS fellow in 2011.
His research interest is on the investigation of emerging phenomena at surface, in reduced dimensionality, and at nanometer scale. Specific interest includes magnetism and electronic transport of nanostructured materials and complex oxides, and their underlying physical mechanism.
So far he has written five review articles for Surface Science, Surface Science Report, and J.Phys: Condensed Matter on low-dimensional magnetism. He has given over 100 invited talks at international conferences including APS, AVS, MRS, MMM, Intermag and ICM. His past research has received a number of awards including 2003 US Presidential Early Career Award for Science and Engineering (PECASE), the Otto-Hahn Medal from Max-Plank Society in Germany, the National Chair Professorship from Chinese government, the oversea outstanding young researcher award from Chinese NSF, and the Wigner fellow from Oak Ridge National Laboratory.
