Abstract
An instrument for visualizing and determining the, direction of local two-dimensional magnetic fields by a magneto-optical technique has bee n built. Using ferrite-garnet films in the homogeneous rotation mode, we achieved a response time to a magnetic-field change of less than 10 nsec without a notable drop in the magnetic susceptibility. The minim um measurable magnetic field intensity was 10(-6) Oe. The spatial reso lution was limited by that of the optical system and was 3 mum.
