Microstructure and electromagnetic properties of Ca–V co-doped YIG ferrite with narrow ferromagnetic resonance linewidth
Yttrium iron garnet (YIG) ferrites play a crucial role in microwave devices due to their tunable saturation magnetization and narrow ferromagnetic resonance (FMR) linewidth. In this study, we successfully synthesized Ca–V co-doped Y2.7−2xCa0.3+2xFe4.7−xZr0.3VxO12 (0.00 ≤ x ≤ 0.35, ∆x = 0.07) ferrite and conducted an in-depth investigation into its microstructure and electromagnetic properties. The findings indicate that moderate ionic substitution can effectively reduce the porosity and FMR linewidth while enhancing the saturation magnetization and resistivity. In particular, the occupation rate of cation sites was comprehensively analyzed, and the separation of the FMR linewidth was calculated. At a substitution level of x = 0.07, the YIG ferrite exhibits excellent comprehensive performance, where the sample has a bulk density of 4.968 ± 0.011 g/cm3, a saturation magnetization of 1932 Gs, an FMR linewidth of 28.80 ± 1.25 Oe, a coercivity of 2.24 Oe, and a DC resistivity of (3.50 ± 0.37) × 106 Ω•m. The Ca–V co-doped CaZr-YIG ferrite exhibits not only superior overall performance but also considerable potential for integration into microwave component design.
期刊介绍：
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
