PURPOSE
In the research area of “Spintronics”, many fascinating discoveries and inventions have been provided by sake of enthusiastic efforts of the researchers. Those findings/inventions, such as giant magneto-resistance effect (GMR), tunneling magnetoresistance effect (TMR), spin-transfer effect, are too numerous to be mentioned. Most of those discoveries are, however, limited to the phenomena that are based on a fluid dynamical aspect of conserved spin-current and its interaction with local spin-moments.
In this aspect, the spin-orbit interaction (SOI), that is a main topic of this workshop, only acts as an obstacle to maintain spins. The SOI is an interaction of spins with velocity dependent magnetic field inside crystal and is very sensitive to the local atomic arrangements and symmetry. Therefore, a control of the effect was thought to be one of the most difficult issues. Recently, however, researchers started to control local symmetry in nano-scale and succeeded to extract phenomena caused by SOI. Those results are now providing us with better understanding about historical problems, such as anomalous Hall effect and current induced domain wall motion. Further, researches in SOI now growing as a new area of science, in which we investigate spin Hall effect, Rashba-torque, voltage control of magnetic anisotropy (VCMA), Dyzaloshinskii-Moriya interaction (DMI), non-trivial
skymion phase, and other fascinating phenomena.
The workshop are planned to discuss those new phenomena related to SOI in spintronic systems. For this purpose, we call distinguished researchers from Korea and Japan where the research in SOI has been most developed.
The workshop also aims to provide a chance to know each history and culture better and to promote scientific collaboration between Korean and Japan.
