1. Title: Exploring the dynamics of magnetic order and its excitations using magneto-optics
2. Speaker: 이 창 민 교수님 (한양대학교 물리학과)
3. Date & Time: Oct 4(Wed.) 2023. 4:30 PM
4. Place: Natural Science 1, Room No. 31214
5. Abstract: Harnessing spin degrees of freedom is a central goal of condensed matter physics and materials science. In pursuit of this objective, this colloquium will first discuss the basic principles of magnetic materials, domain walls, and spin waves. In particular, the talk will focus on how magneto-optic microscopy and ultrafast spectroscopy can be used to explore the dynamics of electron spins through light-matter interaction and time-resolved optical probes [1-3]. By providing a comprehensive overview of this exciting research field, the talk will demonstrate the potential of time-resolved magneto-optic microscopy for advancing our understanding of fundamental magnetic phenomena and developing new technologies for data storage and processing.
