Abstract
The effect of the indium dopant on the magnetic properties and crystal structure of M-type barium hexaferrite was studied. Relying on Mossbauer spectroscopy data and magnetic measurements, the distribution of the dopant ions in the sublattices and their effect on magnetic characteristics were established. The dependences of specific magnetization and coercivity on the location of indium ions in the hexaferrite crystal structure and on the indium ion content were determined. Weakening of the exchange interaction between the sublattices at the replacement factor x = 0.6 and change in the magnetic moment orientation determined by the angle θ were revealed.
