Investigations of the magnetic field induced linear and circular birefringence in the antiferromagnetic magnetoeleclric crystal LiCoPO4 were performed. A step-like change at H~20 kOe accompanied by magnetic hysteresis possessing high-field long tail was revealed. The behaviour of induced birefringence points to the magnetic field induced spin-reorientation phase transition to a non-collinear incommensurate structure.

Key words: liquid crystal, lyotropic system, sponge L3 phase, surfactant, reflection ellipsometry, total internal reflection, surface ordering
