장소 Room 1323, KAIST Natural Sciences Lecture Hall(E6) 
Tokyo Institute of Technology 소속 Takehito Yokoyama 교수님을 모시고 'Physics of ferromagnet/superconductor junctions' 주제에 대한 세미나를 개최하고자 합니다. 
물리학과 구성원 여러분들의 많은 참여 부탁드립니다.
 
1) Time :  at 16:00 on Feb 20, 2023 
2) Venue : Room 1323, KAIST Natural Sciences Lecture Hall(E6) (자연과학동 1323호)  
3) Speaker : Prof. Takehito Yokoyama (Tokyo Institute of Technology) 
4) Talk Title :  Physics of ferromagnet/superconductor junctions 
5) Abstract
    -  Ferromagnet/superconductor junctions offer an interesting platform to study interplay between ferromagnetism and superconductivity such as emergent odd triplet superconductivity, magnetization dynamics, spin torques and vortices in superconductor junctions[1]. Reviewing this field, in particular superconducting spintronics, I will talk about some of my works on these junctions[2].
