Co, Ti, Mn-precipitated barium hexaferrite powders

摘要

Barium ferrites substituted by Co, Ti, and Mn, produced by the citrate method have been studied. The substitution x in BaCo/sub x/Ti/sub x/Mn/sub y/Fe/sub 12-2x-y/O/sub 19/ 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.
