“…12 Over the past several decades, several works on replacing YIG garnet with other metal ions have been reported; these studies revealed that the structural, morphological, | 813 CAO et Al. 16,17 Aldbea et al have shown that the Fe 3+ ions replaced by Al 3+ ions can improve the coercive field while decreasing the saturation magnetization and dielectric properties. 13,14 For instance, Chen F. et al have reported that the substitution of the Fe atoms with the Zr atoms at the 16a position can decrease the permeability and magnetic loss in the 1 to 100 MHz range.…”

“…15 Also, Peña-Garcia et al have found that Zn atoms replace the Fe atoms, increasing the crystal parameter with the concentration of dopant ions, and diminishing the magnetic moment. 16,17 Aldbea et al have shown that the Fe 3+ ions replaced by Al 3+ ions can improve the coercive field while decreasing the saturation magnetization and dielectric properties. 11 Guo et al confirmed that a replacement of the iron ions at the 16a position in YIG with an appropriate amount of the In 3+ ions significantly reduce the magnetic anisotropy and coercivity of YIG.…”

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).

Chromium substituted polycrystalline Yttrium Iron Garnets (Y3Fe5–xCrxO12 with x = 0 to 0.5) were prepared in single‐phase form with lattice constant in the range of 12.3775 Å to 12.3560 Å. All samples exhibit ferrimagnetic transition with transition temperature (Tc) in the range of 547 K for x = 0 to 494 K for x = 0.5. The saturation magnetization value at room temperature is found to increase with Cr concentration that is, from 24.8 to 26.6 emu/g and this is attributed to the preferential occupation of Cr3+ ions at octahedral site of Fe3+ ions. The frequency dependence of impedance data shows the relaxation and thermal activation of charge carriers across grains and grain boundaries. The complex impedance spectra were modeled by considering equivalent circuits having contributions from the resistance and constant phase element due to grains and grain boundaries and capacitance across grain boundaries. The dielectric constant is found to increase from 20 to 52 as the Cr concentration is increased and it is attributed to hopping of charge carriers across Fe2+–Fe3+ centers. The Arrhenius plots of relaxation time of charge carriers and conductivity show an anomaly in the vicinity of ferrimagnetic transition temperature and it highlights the presence of magneto‐electric coupling.
