In our unit, we aim to investigate intriguing emergent phenomena in magnetic topological materials and strongly correlated electron system, with a particular emphasis on “extreme” conditions previously unattainable in earlier experiments. For instance, we employ microfabrication techniques on single crystalline quantum materials using focused ion beams (FIB). This enables us to (i) perform precise magneto-transport study under ultra-high pressure, (ii) explore magnetization dynamics in spin textures under high-density currents, and (iii) manipulate carrier densities in bulk layered materials through ion intercalation. Through these innovative approaches, we aim to reveal new quantum phases and elucidate their electronic functionalities.
