Abstract
On the basis of a recently developed theory, taking into account the f inite energy of the orientation coupling between the suspended ferropa rticles and the nematic carrier, the magnetic Fredericksz transition ( the instability of a uniform texture) taking place in flat layers of f erronematic mixtures is studied. The dependence of the threshold field strength upon the main reference parameters - surface energy density, particle size and concentration - is determined.
