摘要：
The influence of flexoelectric polarization induced by external electric and magnetic fields in a ferronematic liquid crystal on the orientational transitions between uniform and nonuniform phases is analyzed. The Freedericksz transition field and the saturation field as functions of ferronematic material parameters are determined. Bifurcation diagrams of orientational phases are analyzed. It is shown that the orientational transitions can be of the first or second order depending on the value of the segregation parameter of the dispersed phase.
