Annotation: The composite materials have opened a new trend for multifunctional materials. In particular, barium hexaferrites can be applied in order to improve electromagnetic properties in composites. In this article, we present the results of the study of composite radiomaterials. The polymerization process was held in an external magnetic field. Magnetic materials with a texture based on barium ferrite were obtained. Reflection coefficient and imaginary permeability spectra are measured in the range of 0.02-4 GHz. The increase in values of magnetic characteristics for textured magnetic material is shown. The value of imaginary part of permeability of texture samples is 1.3 times more than of original samples.
