Outline of Research at the Start

Scanning diamond NV spin probe microscopy is employed to image spin waves propagating within a nanometer-width magnetic domain wall channel. Leveraging the atomic size of the NV center, the scanning diamond NV probe offers capabilities unable to be achieved by conventional spin wave imaging methods.
