Abstract

Visualization and quantitative mapping of the static inhomogeneous magnetic fields by means of new magnetooptical method is described. The method is based on domain structure in Bi-substituted iron-garnet films to obtain the distribution of field component normal to film plane and averaged over film thickness. Theory of the method is outlined. Two configurational kinds of the domain structures are defined to gain simple mapping rules and direct visualization of field distribution in film plane. It's shown for example the way of investigation of field produced by miniature permanent magnets.
