TEORETICAL BASES OF MAGNETOOPTICAL REFRACTOMETRY FOR TRANSPARENT MEDIA

This article discusses the possibility of applying the odd magnetooptical effect in transmitted light on the two-layer ferromagnetic-film–transparent-substrate system in order to determine the refractive index of the substrate. This phenomenon is also known as the Mayevsky-Druzhinin effect (MDE). The article provides a brief description of the MDE, in particular, its peculiarity in the angular dependence – the sign change at the Brewster angle of the substrate. The traditional method of angle determination is inferior in a number of characteristics to the one proposed in this paper, and this makes the MDE method promising for use in refractometry.
