Professor Hatsujiro Hashimoto is one of the pioneers in imaging crystalline solids by transmission electron microscopy (TEM). His many achievements include the development of TEM instruments and holders, pioneering work in atomic-scale imaging and early contributions in understanding diffraction contrast based on dynamical diffraction theory. In addition, Professor Hashimoto performed in situ observations at elevated temperatures as high as 3000oC in the 1960s, fabricated an environmental TEM instrument with a gas reaction chamber and challenged the field to image single atoms using spectrometry techniques in TEM. His tremendous scientific contributions influenced scientists not only in Japan but also across the world. This symposium is dedicated to the memory of Professor Hashimoto and will feature technical aspects spanning a broad range of topics representative of the significant breadth and scope of his work and achievements.

A02 - Atomic-scale Functional Imaging in Aberration-corrected Electron Microscopy

In this symposium, transmission electron microscopy techniques for imaging magnetic fields, such as Lorentz microscopy, differential phase-contrast (DPC), electron holography, and electron energy-loss magnetic chiral dichroism (EMCD), are emphasized. As functional magnetic materials continue to decrease in size, surfaces and interfaces play a growing significance on novel nanoscale magnetic phenomena. Further, skyrmions and topological insulators have recently received widespread interest leading to an increasing demand for high resolution quantitative magnetic measurements in combination with local structural characterization. With recent advances in mind, the goal of this symposium is to bring together experimentalists involved in applying/developing magnetic techniques and those involved in simulations and/or the development of theory to explain quantitatively magnetic phenomena with TEM.
