Anisotropy of the Linear Magnetic Birefridence of Europium Iron Garnet

Abstract:

The results of investigation of magnetic linear birefringence (MLB) and magnetic linear dichroism (MLD) of Eu₃Fe₅O₁₂ (EuIG) iron garnet on ⁷F₀ ⁷F₆ optical transitions upon variation of the directions of the magnetization vector I relative to the electric vector E linearly polarized light that propagates through single crystal iron garnets are presented. The measurements were made on Eu₃Fe₅O₁₂ single-crystal samples in the form of plates 100 μm thick cut in the (110) and (100) plane at the temperatures T = 82 and in a magnetic field H= 25 kOe. The absorption spectra of the linearly polarized light were studied. It is shown that MLB and dichroism in the region of the ⁷F₀ ⁷F₆ absorption band reach values 10^-3. First experimentally discovered nonreciprocity of MLB spectra and dichroism with the change of the relative orientation of the magnetization vector I and the light wave vector. This effect may use as a base for the design of the different transducers, for example, magnetooptical optical channels commutator.
