He was also previously a Senior Scientific Research Specialist of the Ministry of Education, Culture, Sports, Science and Technology and is currently a Program officer at JSPS Research Centre for Science Systems. Professor Suemasu has published more than 480 research articles and has an h-index of 45 (Web of Science).
Summary
Since the discovery of perpendicular magnetic anisotropy in Mn4N epitaxial films in 2012, Mn4N has attracted much attention as a rare-earth free new spintronics material. The recent record velocity of current-induced magnetic wall motion achieved on Mn4N and compensated Mn4N microstrips at room temperature has attracted a great deal of attention, and spin transfer torques have renewed interest. Mn4N shows interesting phenomena that magnetization and angular momentum compensation due to impurity doping occur at room temperature. It also has other very unusual properties such as a negative thermal expansion coefficient. In addition, a very large number of different kinds of mixed crystals have been formed. Specifically, they include Mn4N doped with various impurities (Fe, Co, Ni, Cu, Zn, Al, In, Ga, Ge, Sn, Pd, Ag, Sb, Pt, Au, Gd, and Dy).
