Monte Carlo
simulations to obtain physical properties of magnetic systems

Ryo Tamura

The
magnetic material is widely used not only in industrials but also in medical
services and is indispensable for our life. In general, physical properties
induced in magnetic materials are characterized by the magnetic structure.
Then, to clarify a relationship between magnetic structure and physical
property is one of the central issues in physics, chemistry, and materials
science. Furthermore, to explore a novel magnetic structure is directly
connected to discovery of exotic physical properties and functionalities. At
ICYS, I was searching methods for improving the functionalities and novel
physical properties in magnetic materials by using high-performance numerical
calculations on the supercomputer and analytical techniques in statistical
physics. In this seminar, I will introduce the calculation method based on
statistical physics to obtain physical properties of magnetic systems by
theoretical works. In addition, I will
explain some research activities relating to magnetic systems during ICYS.
