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.

우리는 어쩌다 과학을 믿게 되었을까
저자 이근희, 김갑진
우리가 과학을 신뢰하기까지,
120년 노벨 물리학상이 기록한 위대한 합의의 드라마!
과학자들은 무엇을 의심했고 무엇을 끝까지 포기하지 않았는가?
마치 오케스트라의 아름다운 연주가 한 명의 솔리스트가 아니라 수많은 연주자의 성실한 연습과 호흡으로 완성되듯, 오늘날의 과학 역시 수많은 과학자의 질문과 도전이 쌓여 만들어진 결과임을 자연스럽게 깨닫게 한다. 그리고 과학의 역사는 정답의 역사가 아니라, 질문을 포기하지 않은 사람들의 역사였다는 사실을 새삼 발견하게 될 것이다.
