Abstract: | A possibility of the first-order transition, as well as reentrant transitions, induced by an external magnetic field between
the homeotropic phase and the hybrid homeotropically planar phase in a ferronematic liquid crystal (ferronematic) with bistable
anchoring at the layer boundary is demonstrated in the framework of a continuum theory. The critical values of the material
parameters of the ferronematic, the anchoring energy, the thickness of the layer, and the magnetic field strength, for which
this transition is possible, are determined. The cases of positive and negative diamagnetic anisotropy of the ferronematic
are considered. |
