Abstract
The magneto-optical transverse Kerr effect of a 50 nm thin iron film i s used to modulate (modulation index 3%) Light beams up to 100 kHz. Th e displacement between two light spots is measured by the time differe nce of the corresponding photodetector signals. At a total light power of 5 mu W a local resolution of 29 nm is achieved.
