Popis: This paper presents the optical study of the magnetically induced change of the spatial orientation of the directors' field in a ferronematic. This paper presents the investigations of the ferronematic that base on 6CHBT nematic liquid crystal. Magnetic field induces one-dimensional distribution of the tilt angle of a directors filed. On a basis of the optical measurements the mean volume concentration of magnetic particles was determined. Moreover the range of magnetic field intensity was determined in which the distribution of tilt angle can be described in scope of the Burylov-Raikher theory and the small tilt angle approximation.
