The Magnetic Field

We explain the motion of a micron-sized ferromagnetic disc immersed in a nematic liquid crystal under the action of a weak magnetic field using numerical simulations. We show that the disc's behaviour can be controlled by the angular speed of the magnetic field and its magnitude.

Good Agreement

The influence of a magnetic field of variable strength and direction on the deformations and the electric conductivity of a nematic liquid crystal is treated theoretically. The results are in good agreement with measurements of the electric conductivity of MBBA, doped with tetrabutylammonium picrate. The bend and the splay elastic constants of MBBA are found to be k33 = 8.62 · 10-7 dyn and k11 = 6.38 · 10-7 dyn at 22.1 °C.
