“…Evidently, In 3+ doping leads to a reduction in linewidth and Gilbert damping coefficients, as In 3+ occupancy at the 16a sites diminishes inter-domain magnetic coupling and promotes spin wave transmission, whereas Ga 3+ occupancy at the 24d sites exerts an opposing effect. These findings are in good consistence with previous reports [17,18,34,35]. Conversely, the linewidth and damping of FMR typically reflect the dissipation of energy during the precession of the magnetic moment in the film.…”

“…The FR temperature coefficient could potentially be further regulated by controlling the three magnetic sublattices in garnet, thus addressing this issue; however, no definitive experimental conclusion has been reached yet. Building upon prior research on ion-doped garnet [15][16][17][18][19][20], distinct ions would be selectively incorporated into the sublattice that best aligns with their properties. So, in this study, nonmagnetic yttrium (Y) and magnetic holmium (Ho) were employed to occupy the 24c sites, resulting in the formation of CeY 2 Fe 5 O 12 (Ce: YIG) and CeHo 2 Fe 5 O 12 (Ce: HoIG).…”

Cerium doped rare-earth iron garnet (Ce: RIG) film is a promising candidate for magneto-optical devices in laser systems with giant Faraday effect; nevertheless, devices fail nonreciprocally with increasing temperature due to a negative Faraday rotation angle temperature coefficient. To mitigate this effect, the relationship between the magnetic moments of three distinct magnetic sublattices and the temperature coefficients of the Faraday rotation angle was investigated. Cerium doped holmium iron garnet (Ce: HoIG) film, where magnetic Ho3+ occupied the dodecahedrons, exhibited an enhanced Faraday rotation angle retention at a temperature of 400 K. However, the nonmagnetic ion doping in tetrahedral and octahedral sites yielded a negligible effect. The mechanism behind this occurrence is attributed to the magnetic compensation effect, which results in a small magnetic moment temperature coefficient within the range of 300 - 400 K. The study not only offers strategies for designing Ce: RIG components with reduced temperature coefficient, but also presents the development of a Ce: HoIG film exhibiting promising stability in Faraday rotation angle as a function of temperature.

“…Studies on Sm‐doped YIG indicated that the saturation and remanent magnetization decreased with increasing Sm concentration 15 . The doping of In ions in YIG ferrite can effectively reduce the FMR linewidth 16 . The FMR linewidth represents the microwave magnetic loss performance of YIG ferrite, and microwave dielectric properties considerably influence microwave loss.…”

Herein, the crystal structure, dielectric properties, and gyromagnetic characteristics of Zn–Sn codoped Y3ZnxSnxFe5−2xO12 (x = 0.0–0.5) prepared using a conventional ceramic process were investigated. According to the first‐principles’ calculations and complex crystal bonding theory, Zn2+–Sn4+ codoping can increase the relative dielectric constant (εr) by enhancing the average ionicity. The x‐ray photoelectron spectroscopy (XPS) and Raman analysis results indicate that an appropriate amount of Zn2+–Sn4+ codoping can help improve the microscopic morphology, maintain the appropriate ratio of divalent iron ions, and reduce the microwave magnetic and electrical losses of YIG ferrites. The optimized microwave properties are as follows. Y3Zn0.3Sn0.3Fe4.4O12 after sintering at 1400°C; εr = 15.6; dielectric loss, that is, tanδε = 4.3 × 10−4; saturation magnetization, that is, 4πMS = 2244 G; ferromagnetic resonance linewidth, that is, ΔH = 37 Oe. These properties can help improve the performance of high‐frequency microwave components by enhancing the properties of ferrite.
