Abstract

Here we report the introduction of multiferroic BiFeO₃ nanoparticles in a 5CB nematic liquid crystal host having positive dielectric anisotropy. The BiFeO₃ nanoparticles had an average diameter of *50 nm and were prepared by modified Pechini method. Its effect on the Schlieren Texture and the formation of the isolated stripe domains was observed under optical polarizing microscope. When the sample was poured into a 90° twisted nematic cell and observed under an optical polarizing microscope in cross polarizer configuration it yielded normally black state in contradiction to the expected normally white and remains unchanged even with the application of external voltage. The polarizing microscope photograph of the cell observed under parallel polarizer configuration suggests the accommodation of the nanoparticles along the cell wall grooves.
