Abstract :
Barium ferrites substituted by Co, Ti, and Mn, produced by the citrate method have been studied. The substitution x in BaCoxTixMnyFe12-2x-yO19 has been varied from 0.2-2.O i./f.u. and the substitution of Mn y=0.1 i./f.u. Magnetic parameters were measured by the vibration magnetometer. The mechanism of hexagonal structure formation has been checked by Mossbauer spectroscopy
