520 _aThe main study in the thesis is the investigation of the structure electric and magnetic properties of three groups W-type hexagonal ferrites samples with different compositions: A first group with the formula BaCoZn1-xMgxFe16O27;0-<X-<0.6. These super properties of this composition open a new area and a wide range of applications
