“…Second, new internal electric dipole moments were formed due to the different charges of Zn 2+ and Zr 4+ . 34 Table 2 gives the values of M s for the samples with different doping ratios, indicating that M s is affected by the doping ratios. Figure 6B shows the change of the imaginary part of the complex dielectric constant (ε″) with the frequency at different doping concentrations.…”

“…Figure 8 shows the hysteresis loop of the Y 3 Zn x Zr x Fe (5−2x) O 12 ceramics at different x; these ceramics, such as YIG, have small coercivity (less than 50 Oe) and are typically soft magnetic materials. 34 Table 2 gives the values of M s for the samples with different doping ratios, indicating that M s is affected by the doping ratios. At a low doping concentration (x ≤ 0.1), M s remains stable at approximately 24.7 emu/g, which is close to the theoretical value.…”

In this study, yttrium iron garnet co‐doped with Zn and Zr atoms with a chemical formula Y3ZnxZrxFe(5−2x)O12 (x = 0.0‐0.3) has been successfully prepared by the solid‐state reaction method. The effects of doping concentration on the microstructure, crystal structure, magnetic properties, and dielectric properties of Y3ZnxZrxFe(5−2x)O12 were investigated. The microstructure analysis indicates that co‐doping of YIG with Zn and Zr can effectively reduce the grain size of the ceramic. The crystal structure results reveal that the doping concentration of Zn–Zr has substantial influence on the lattice parameters of YIG, such as, increases the lattice constant, crystal cell size, and interplanar spacing. However, the second phase of ZrO2 appears once x ≥ 0.15. Additionally, the dielectric properties of YIG ferrite can be regulated using this Zn–Zr co‐doping method. Zn–Zr co‐doping can improve the dielectric stability and reduce the dielectric loss at high temperature. The magnetization measurement shows that the saturation magnetization is stabilized at x < 0.15, and the magnetic loss is decreased with the increase in the doping concentration. Overall, the findings show that the ceramic with x = 0.1 exhibits better properties included high saturation magnetization (24.607 emu/g), low magnetic loss (0.0025 @ 1 MHz), and relatively low dielectric loss (496 @ 400°C).
