摘要: Orientational transitions induced by an external magnetic field in a ferronematic (a suspension of single-domain particles nematic liquid crystal) are considered the framework continuum theory. The surface potential interaction between and bounding plates is used taking into account fourth-order anisotropy (the modified Rapini potential). It shown that can be one three phases correspond to types orientational ordering: homogeneous ordering, inhomogeneous saturation state. influence segregation effect on nature studied. established these first second order depending values anchoring parameters parameter. Tricritical parameter determined.
