Abstract
In-doped BaFe11In1O19 particles were prepared by a modified ceramic reaction using In2O3, BaCo3, and Fe2O3 followed by mechanical dispersion. X-ray diffraction analysis confirmed the formation of pure BaFe11In1O19 phase and scanning electron micrographs showed platelet particles of about 1μm in diameter. This powder was subsequently screen printed on alumina substrate using a suitable binder and oriented under a dc magnetic field of 15kOe. The screen printed films were annealed at different durations to produce dense and thick ferrite materials. The hysteresis loops for the as-prepared and annealed screen printed, in-plane oriented films show a hysteresis squareness ratio (Mr∕Ms) of 0.93, saturation magnetic moment of 4000G, and coercivity of 634Oe. The ferrimagnetic resonance measurements showed a linewidth (ΔH) of ∼860Oe. The g (Lande spectroscopic splitting factor) value deduced from the relation between resonant frequencies versus resonance field for the screen printed films was found to be 1.91.
