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 1 μm in diameter. This powder was subsequently screen printed on alumina substrate using a suitable binder and oriented under a dc magnetic field of 15 kOe. 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 4000 G, and coercivity of 634 Oe. The ferrimagnetic resonance measurements showed a linewidth (ΔH) of ∼860 Oe. 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.
