Magneto-optical investigation of MgSO3·6H2O with polarized light

The crystals of magnesium sulphite hexahydrate (MgSO3·6H2O) belong to point group C3 (no center of symmetry). They possess gyrotropy and nonlinear optical properties. The refractive index no and ne, the angle of Faraday rotation φ(λ), the Verdet constant V(λ), the magneto-optic anomaly factor γ(λ) and the density of oscillators N of MgSO3·6H2O single crystals have been studied in the present work. The investigations were carried out in the spectral range 300 - 800 nm with linear polarized light E⃗⊥c̅ , E⃗||c̅ (c̅ is the optical axis of MgSO3·6H2O) propagated in the direction (101̅0).
