Typical -wall connecting two disclinations and parametrization of the director field.
(Color online) Transmitted intensity under crossed polarizers at and . Crosses are experimental values. Full and dashed lines correspond, respectively, to the best fit with Eq. (4) and to a plot with .
(Color online) Zenithal anchoring torque vs the zenithal angle . Dots are experimental values (irrelevent below 45°), and full line is the best fit with the Rapini-Papoular expression.
(Color online) Azimuthal anchoring extrapolation lenght of NOA60 vs UV exposure dose at . The error bar represents the dispersion of experimental values: different regions on the same cell.
-wall at different temperatures [(a) , (b) , and (c) ].
(Color online) Variations of the azimuthal anchoring extrapolation lenght of NOA60 with the temperature for different exposure doses .
Variations of the surface pattern with the exposure time to magnetic field , with [(a) , (b) , and (c) ].
