We report our studies of magneto-optical properties of dispersions of dichroic elongated plate-shaped pigment particles
We showed that this system displays a rich variety of phenomena, such as mesophase behaviour, electro-optical response, and pattern formation in electric elds.[14,15,16]
Summary
We demonstrate an unusually strong magneto-optical response of elongated plate-shaped pigment particles in magnetic fields ranging from 0 to 25 T. Most other suspensions of anisometric particles studied, such as fd and tobacco mosaic viruses, gibbsite platelets, and plate-shaped biological membranes and cells, behave as diamagnetic and do not exhibit any appreciable magneto-optic effects at low and moderate magnetic elds.[6,7,8,9,10,11] Yet, a combination of anisotropic so non-magnetic materials with enhanced optical properties, such as liquid crystals and magnetic uids, opens up the possibilities to develop novel multifunctional and multiferroic materials.[12,13] We report our studies of magneto-optical properties of dispersions of dichroic elongated plate-shaped pigment particles.
