Abstract Scope |
M-type barium hexaferrites (BaM) have attracted a lot of attention due to their multiferroic and other functional properties. Doped M-Type Barium hexaferrite, BaFe12-xTxO19, where T = Sc with x = 2.5 has been investigated. XRD analysis reveals that the samples are in a single phase with space group P63/mmc. Magnetization curves in the temperature range of 5 K to 750 K indicate several transitions for the BaFe9.5Sc2.5O19. Transitions observed at lower temperatures indicate antiferromagnetic order. Temperature dependence neutron diffraction measurements performed at a wavelength of, λ = 2.315 Å, in the temperature range 3 K – 300 K. Magnetic satellite reflections start appearing at low angles on decreasing temperature, refinement of this magnetic reflection indicates the presence of conical magnetic structures at low temperatures. This indicates, that the direction of magnetic moments, compared with the parent compound, is no longer along the hexagonal c-axis. |
