The manuscript contains data on the effect of the Co content on the magnetic properties of Zn0·3Ni0·7Fe2O4 spinels, in which Ni2+ ions are partially substituted by Co2+ ions. Ferrites were produced via solid-state reaction from a mixture of oxides.

Using Mossbauer spectroscopy, magnetometry and X-ray diffraction, we have studied the BaYxFe12 – xO19 hexaferrite (0.1 ≤ x ≤ 1.2). The low isomorphic capacitance of hexaferrite is shown, which leads to phase separation with the formation of В
