Zhigao Sheng: Introduction of Chinese High Magnetic Field Laboratory and Visualization of Multiply-ordered Electronic Crystals
|When:||Mo 20-02-2017 15:00 - 16:00|
In the talk, I will briefly introduce the steady High Magnetic Field Laboratory in Chinese Academy of Science (CHMFL) to you, including magnets, experimental setups, and recent progress.
Moreover, one recent study on electronic crystals by magnetic force microscope in high magnetic field will be presented. Lattice and electrons determine the matter properties together and they can form long-range order crystals, respectively. Distinguishing and isolating the electronic crystal out from the lattice crystal is a crucial and outstanding issue in condensed mater physics. In the talk, we will show the first-time observation of multiply-ordered electronic crystals and their dynamics in a manganite film using a home-built 20 T magnetic force microscope. They have well-defined boundaries along specific axes and cleavage planes during their formation and annihilation processes, which is associated with the simultaneous orderings of the electron degrees of freedom. They are parasitic inside the lattice crystal house, but their dynamics follows intrinsic rules of electronic correlation, which confirms the distinguishability and isolability of the electronic crystal.
