Gy. Ivanyuk et Mg. Tomilin, USING NEMATIC LIQUID-CRYSTALS TO VISUALIZE MAGNETIC DOMAINS ON THE SURFACES OF MATERIALS, Journal of optical technology, 61(4), 1994, pp. 315-318
A contact optical-polarization method has been developed for visualizi
ng magnetic domains, based on the use of nematic liquid crystals. It i
s shown that it can be used to visualize magnetic domains in minerals
and materials for storage systems with high data-recording density.
