Description:
Scattering-type scanning near-field optical microscopy (s-SNOM) is a key technique in our group. By using a sharp metallic tip to confine and scatter optical near fields, we access optical responses on the nanometer scale from the infrared to the visible. This allows us to directly measure local electronic and magneto-optical properties in complex materials well below the diffraction limit.
Our research focuses on magnetism and spintronics. We explore spin-dependent phenomena, magneto-optical responses, and ultrafast magnetic dynamics with high spatial and temporal resolution. A particular emphasis is placed on compensated and antiferromagnetic systems, whose subtle magnetic order requires nanoscale-sensitive probes. Our work provides fundamental insight into antiferromagnetic spin textures and nonequilibrium dynamics, contributing to the development of next-generation spintronic and information technologies.
