“…The value of anisotropy energy constant such materials exceed values of garnet ferrites in a hundred times more. Such excellent functional properties made it possible their practical applications as permanent magnets [8], magnetic recording media [9], and microwave devices. Hexagonal ferrites are successful used in absorption of centimetric radio waves.…”

a b s t r a c tThe investigations of the crystal and magnetic structure by powder neutron diffractometry as well as the magnetic properties by vibration sample magnetometry for the BaFe 12 À x In x O 19 (x ¼0.1-1.2) solid solutions have been performed at different temperatures and magnetic fields. The atomic coordinates and lattice parameters have been Rietveld refined. The Invar effect has been observed in low temperature range (from 150 K to 10 K). It was explained by the thermal oscillation anharmonicity of atoms. The increase of microstress value with decreasing temperature has been defined from Rietveld refinement. The Curie temperature and change of total magnetic moment per formula unit have been defined for all the compositions of the barium hexaferrites BaFe 12 À x In x O 19 (x ¼ 0.1-1.2) solid solutions. The magnetic structure model is proposed. The most likely reasons and the mechanism of magnetic structure formation are discussed.
