Abstract

We consider the effect of magnetically controlled anchoring of ferro-nematic suspensions. Together with co-authors we recently found that application of weak magnetic field to a cell filled with the ferro-suspension induced an axis of easy orientation of the director of liquid crystal on a polymer surface (Mol. Cryst. Liq. Cryst., 375, 81, (2002). Here we present a simple theoretical model of the effect that assumed coupling between liquid crystal and the applied magnetic field. This coupling is assumed to be a combination of the interaction between magnetic field with ferro-particles magnetic momentum on the one hand and LC director anchoring with these particles on the other hand.
