Abstract
Electrorheological (ER) effects in the nematic (Ne), the smectic A (SmA) an d the isotropic (Is) phases of octyloxy cyanobiphenyl (8OCB) are studied. W hen an electric field is applied, a large decrease of the viscosity is obse rved in the Sm A phase, while in the Ne phase an increase of the viscosity is recognized with an anomalous ER effect near the SmA-Ne phase transition. These behaviors are suggested to be general properties of the liquid cryst al exhibiting the phase sequence of SmA-Ne-Is.
