Associate Professor Yasutomi Tatetsu / University Center for Liberal Arts Education, Meio University

Yasutomi Tatetsu completed his Ph.D from University of the Ryukyus (Supervisor: Takahiro Maehira) in 2013, and joined the Elements Strategy Initiative Center for Magnetic Materials (ESICMM) as a postdoctoral at The University of Tokyo and Tokyo Institution of Technology from 2013 to 2018. He currently works at University Center for Liberal Arts Education and Institutional Research Center in Meio University. He has an interest in computational approaches to magnetic materials, new materials to solve energy issues, and strong correlated f-electron systems.

[Title] 

First-principles study for material science 

[Abstract]

irst-principles calculation based on density functional theory is known as one of the most useful methods to compute electronic states of materials. This calculation method is widely used to find novel materials and to understand new physics by developing high-performance-computing infrastructures. There is growing demand for developing high performance magnetic materials, in order to achieve sustainable development goals since these materials are utilized in a variety of computers, machines, vehicles, etc. In this talk several computational studies on magnetic nanoparticles, surfaces and grain boundaries of materials, especially Nd-Fe-B sintered magnets, which are known as the strongest permanent magnets, will be presented.
