“…The film is the thinnest film (122.8 nm) compared to other films. The slight reduction in transparency of the sample (y=1.4) which has the smallest grain size is mainly due to reflection losses [39]. However, the obtained results are higher than the result reported (90 %)…”

Abstract. The combined substitution of Tb and Er ions at the yttrium site with a formula Y 3-x-y Tb x Er y Fe 5 O 12 , (x = 0.0, 0.2) and (y = 0.0, 0.2, 0.6, 1.0 and 1.4) were prepared by a sol-gel method. The crystalline structures of all films were found to have a pure single phase garnet structure. This result confirmed the successful incorporation of erbium and terbium ions into YIG structure. The lattice constant increased linearly with Er +3 concentrations from 12.379 to 12.532 Å. The morphology measurement revealed the formation of nanoparticles films. The magnetic properties characterization exhibited that all films are soft ferrimagnetic materials .The results showed the saturation magnetization Ms of pure YIG at 150 (emu / cm 3 ). The Ms value decreased to 110 emu / cm 3 at concentration of (x=0.2, y=0.0), then increased with increment of (y) content in a linear manner. The optical transparency of films was over 96 % at (y=0.6) in the wavelength range of 600 to 900 nm. At a short wavelength (λ < 400 nm), absorption coefficient α increased linearly with increment of Er 3+ ions. Because of nearly zero absorption coefficient in the NIR region, the films could be useful as optical isolator.

“…For such applications, a higher FE is desirable, which allows for the miniaturization of the device [7,9]. With the substitution of yttrium with bismuth or rare earth elements such as cerium, it is possible to enhance the FE with only small changes of magnetic moment [10,11], while the garnet maintains its important property as an electrical insulator. The influence of the substitution of bismuth on the magneto-optic properties has been investigated intensively [12][13][14][15], while for cerium only the FE has been studied in bulk [16][17][18] and to a lesser extent for thin films [19][20][21][22][23], However, studies have not been carried out on the magneto-optic Kerr effect (MOKE) in Ce∶YIG, which is relevant for magneto-optic readout applications that are based on reflection geometry.…”

The magnetic and magneto-optic properties of epitaxial CeY 2 Fe 5 O 12 (Ce∶YIG) and Y 3 Fe 5 O 12 (yttrium iron garnet or YIG) thin films grown by pulsed laser deposition on gadolinium gallium garnet substrates are determined. An enhanced Faraday effect is known to result from Ce substitution into the yttrium iron garnet lattice, and here we characterize the magneto-optic Kerr effect, as well as the magnetic hysteresis and ferromagnetic resonance response that result from the Ce substitution. X-ray diffraction analysis reveals a high crystallographic quality for the Ce∶YIG films. Measurements of the magneto-optic Kerr effect for two different wavelengths demonstrate that the Ce∶YIG exhibits an up-to-tenfold increase in Kerr rotation compared to YIG. The Ce∶YIG has a slightly larger magnetic moment, as well as increased magnetic damping and higher magnetic anisotropy compared to YIG with a dependence on the crystalline orientation. By specific cerium substitution in YIG, our results show that the engineering of a large Kerr effect and tailored magnetic anisotropy becomes possible as required for magneto-optically active spintronic devices.
