Ultrafast Nanoscopic Spin Dynamics Lab.

Ultrafast Nanoscopic Spin Dynamics Laboratory is a research group led by Prof. Sug-Bong Choe in the Department of Physics and Astronomy at Seoul National University.

We explore fundamental spin dynamics and magnetic phenomena at the nanoscale, with particular interests in spin–orbit coupling, magnetic chirality, spin-transfer and spin–orbit torques, and the dynamics of magnetic domain walls and skyrmions. Through experimental studies of these phenomena, we aim to deepen our understanding of nanoscale magnetism and explore its potential for future spintronic technologies.
