Introduction

Ultrafast spin dynamics laboratory (USDL) is a research group led by Prof. Kab-Jin Kim of KAIST (Korea Advanced Institue of Science and Techology), department of physics.

We are currently researching on spintronics and magnetism. In condensed matter physics, one of the most important physical property is spin, which is directly connected to magnetism. We are trying to observe and interpretate the spin dynamics in the magnetic materials, and apply it to the development of spintronic memory or logic devices.

Lab. location

Open positions for graduate student

We are seeking highly-motivated students to join us next year! If you want to explore Spintronics, Orbitronics, Magnon hybrid system, Spin textures or Magnetoresistance, don't hesitate to contact Prof. Kab-Jin Kim (kabjin@kaist.ac.kr) 😊
우리와 함께 공부할 열정있는 학생들을 모집하고 있습니다! 스핀트로닉스 분야에 관심있는 학생들은 교수님(kabjin@kaist.ac.kr) 또는 랩장 (백건우, geonwoobaek@kaist.ac.kr)에게 연락주세요 😊

Professor's Book

  마법에서 과학으로: 자석과 스핀트로닉스

저자 김갑진


자석의 근원부터 최첨단 스핀트로닉스까지,
독자의 호기심을 일깨우는 마법 같은 과학책

어렵게만 느껴지던 물리의 재미를 알게 되는 마법 같은 과학책!
왼손 방향 회전 스핀파를 세계 최초로 증명한 물리학자 김갑진,
자석에 이끌리듯 그가 이끄는 대로 질문의 여정을 따라가다 보면
어느새 자석과 전기, 스핀을 이해하게 된다!
