Magnetic domains stripe domain structure

The formation of transient domain patterns aligned perpendicular to the initial director during the relaxation process of the Frederiks transition has been known since the earliest observations by Carr [20] and Guyon et al. [21]. After these observations some other transient domain structures were found in thermotropic and lyotropic liquid crystal with perpendicular [22], parallel [23], oblique [24], and two-dimensional [25] striped patterns relative to the initial orientation of the director in both the electric and magnetic fields. 

Polarization microscopy studies revealed a striped texture of HPC and CEC solutions treated in magnetic field (fig. 7), thus suggesting formation of large supramolecular structures—domains. A similar phenomenon was reported for other polymer-solvent systems (Papkov Kuhchikhin, 1977).
