Fig. 4: Magneto-birefringence effect of 2D CTO in the DUV region.
From: Deep ultraviolet hydrogel based on 2D cobalt-doped titanate
a Optical transmittance of 2D CTO LC (5 × 10–4 vol%) in parallel and orthogonal directions of magnetic field to Poynting vector (P-vector). Insets: optical images of a layered and oriented CTO film sample rotated from the initial state (without magnetic field, left) to the direction parallel to the field (0.8 T, right). b Magneto-birefringence at different concentrations of CTO. c Birefringence as a function of square of magnetic field in the low field range from 0 T to 0.2 T. d Concentration dependent birefringence and transmittance of CTO at 0.8 T
