Research Abstract |
We performed subnanoscale analysis of crystal structures of strongly correlated electron materials and the ordering of the electrons by transmission electron microscopy (TEM). We found formation of nanoscale magnetic bubbles in the orbital-ordered ferromagnetic insulating phase of perovskite-type manganite La1-xSrxMnO3 (x = 1/8) by Lorentz microscopy. In addition, the structures of grain boundaries and defects were revealed for Bi-based high-Tc superconductor (Bi,Pb)2Sr2Ca2Cu3O10+d (Bi-2223) by analysis of the atomic columns using low-voltage aberration-corrected scanning TEM.
