Outline Activities
From April 1988 to March 1998, I worked as an assistant at Interdisciplinary Graduate School of Engineering Sciences. Since April 1998, I have been working as a lecturer in charge of international students, as an associate professor since October 1999. Main research themes: (1) microstructure and magnetic properties of neodymium magnet materials, (2) microstructure analysis of silicide environmental semiconductor thin films, (3) creation and microstructure analysis of new boron-based hydrogen-absorbing alloys, (4) high-pressure analysis using synchrotron radiation X-ray absorption edge structure spectrum measurement, (5) Crystal structure and anomalous physical properties of 4f electron system alloys at low temperature and high pressure, (6) Phase transformation process of long period structure.
In this way, I am conducting research on a wide range of themes, from basic research such as the phase transformation process of alloys to advanced research such as microstructure control of next-generation permanent magnetic materials.
I am involved in the MEXT nanotechnology support project and the JST industry-academia co-creation basic research project and NEDO new high-performance magnet search project, and through these projects I am also engaged in advanced research using ultramicroscopic analysis.
As an educational activity, I have been providing research guidance through the preparation of master theses and doctoral theses for more than 30 years in graduate student education.
In addition, I have given lectures on “Fundamentals of Electronic Physics”, “Fundamentals of Functional Materials Engineering”, and “Advanced Crystal Physics Engineering”.
In undergraduate education, I am also involved in supervising graduation research. In addition, lectures on phase diagrams such as “material structure control theory” and “phase equilibrium theory” and lectures on “Basics of magnetic materials” are given. I am also in charge of lectures on “Fundamentals of Mechanics” and is engaged in fundamental education.
