Influence of the Microdroplets Sizes of Magnetic Emulsions on the Magneto-Optical Effect

Abstract

The features of the magneto-optical effect of optical density change in magnetic emulsions with low interfacial tension, synthesized on the basis of kerosene magnetic fluid and AMG-10 oil, are studied. It is shown that the magnitude and sign of the effect essentially depend on the size of the emulsion droplets. The effect is interpreted on the basis of the anomalous diffraction approximation, and a method is proposed for estimating the size of magnetic emulsion microdroplets depending on the sign of the magneto-optical effect in longitudinal and transverse magnetic fields.
