The implementation of a phase‐modulating polarization detector into a scanning near‐field optical microscope allows the imaging of local magneto‐optic effects with spatial resolution. By taking several pictures at the same location with different detector settings, a quantitative evaluation of magneto‐optic effects, such as Faraday rotation, becomes possible. Images were taken from thin garnet films using this method.©1997 John Wiley & Sons, Ltd.
