摘要
钇铁石榴石(Y3Fe5O12,YIG)铁氧体具有优异的磁性能,适用于微波通信设备。本研究采用固态反应法制备了 Ca-Zr 共取代的 Y1.83-xBi1.17CaxFe5-xZrxO12 (YBiIG,x = 0.00-0.15,步长为 0.05)铁氧体,以增强微波磁性和介电性质。通过 X 射线衍射、扫描电子显微镜、阻抗分析仪、振动样品磁力计(VSM)和铁磁共振(FMR)线宽研究了材料的相形成、微观结构、磁性和介电性质。结果表明,Ca2+-Zr4+离子并没有改变铁氧体的相形成,反而增强了磁导率(\(\mu^{/{prime }}\) = 24.10 at 10 MHz, x = 0.15)和介电常数(\(\varepsilon^{/{prime }}\) = 24.55 at 10 MHz, x = 0.15)。同时,随着 Ca-Zr 取代度的增加,比饱和磁化率(σs)从 20.26 emu/g 增加到 22.79 emu/g,调频线宽(ΔH)从 406.34 Oe 下降到 339.60 Oe。研究结果表明,Ca-Zr 取代的 YBiIG 铁氧体材料所表现出的高介电常数在高频微波器件应用中具有潜在的应用价值,如环行器、隔离器、移相器和其他微波元件。
Enhanced Microwave Magnetic and Dielectric Properties of YBiIG Ferrite by Ca-Zr Co-substitution
Yttrium iron garnet (Y3Fe5O12, YIG) ferrite has excellent magnetic properties that are suitable for microwave communication devices. In the present research, Ca-Zr co-substituted Y1.83−xBi1.17CaxFe5−xZrxO12 (YBiIG, x = 0.00–0.15 with a step of 0.05) ferrites were prepared by a solid-state reaction method to enhance microwave magnetic and dielectric properties. The phase formation, microstructure, and magnetic and dielectric properties of the materials were investigated by x-ray diffraction, scanning electron microscopy, impedance analyzer, vibrating sample magnetometer (VSM), and ferromagnetic resonance (FMR) linewidth. The results showed that Ca2+-Zr4+ ions did not change the phase formation of the ferrites and enhanced the magnetic permeability \(\mu^{{\prime }}\) (\(\mu^{{\prime }}\) = 24.10 at 10 MHz, x = 0.15) and dielectric constant (\(\varepsilon^{{\prime }}\) = 24.55 at 10 MHz, x = 0.15). Meanwhile, the specific saturation magnetization (σs) increased from 20.26 emu/g to 22.79 emu/g with the increase of Ca-Zr substitution, and the FMR linewidth (ΔH) decreased from 406.34 Oe to 339.60 Oe. The work showed that the high dielectric constant exhibited by Ca-Zr-substituted YBiIG ferrite materials has potential application value in high-frequency microwave device applications, such as circulators, isolators, phase shifters, and other microwave components.
期刊介绍:
The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications.
Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field.
A journal of The Minerals, Metals & Materials Society.
