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) …
Epitaxial Growth Of Pbfe₁₂O₁₉ Thin Films By Alternating Target Laser Ablation Deposition Of Fe₂O₃ And Pbo, A. L. Geiler, Y. He, S. D. Yoon, A. Yang, Y. Chen, V. G. Harris, C. Vittoria
Epitaxial Growth Of Pbfe₁₂O₁₉ Thin Films By Alternating Target Laser Ablation Deposition Of Fe₂O₃ And Pbo, A. L. Geiler, Y. He, S. D. Yoon, A. Yang, Y. Chen, V. G. Harris, C. Vittoria

Oriented M-type hexaferrite thin films are deposited using the alternating target laser ablation deposition (ATLAD) technique utilizing PbO and Fe₂O₃ targets. Crystallographic, dc magnetic, and microwave characterization results confirming the presence of a hexagonal PbFe₁₂O₁₉ phase are presented. We conclude that the ATLAD technique holds great promise for layer by layer deposition of various hexaferrite materials, the properties of which can be adjusted by varying the composition of the targets as well as the number of laser shots from each target during the deposition process. This would provide control over the uniaxial anisotropy fields and saturation magnetization values that was …
