Outline of Final Research Achievements

The present study aims to develop a novel method which enables us to measure magnetic properties at sub-nanometer scale, using a focused electron probe and electron energy-loss spectroscopy. This information has never been accessible without large-scale facilities such as synchrotron radiation and neutron diffraction.
As a result of detailed investigation both theoretically and experimentally, we are successful in quantitatively measuring magnetic moments of a material at atomic-plane resolution. In addition, the obtained magnetic signals are found to be localized at the atomic plane that is scanned by the electron probe, which means that a new road is for the first time opened for measuring magnetic properties of any types of magnetic materials in an elemental/atom site-selective way.
