“…The saturation FR angle of STF/Si is approximately 2 times larger than that of STF/ STO, reaching −1900°cm −1 , i.e., the FR scaled with the saturation magnetization. This FR is approximately 60% of that reported for single-crystal cerium-substituted yttrium iron garnet (CeYIG, Ce 1 Y 2 Fe 5 O 12 ) [67,68] at 1550 nm. CeYIG is a candidate material for magnetooptical devices in the near IR.…”

Both polycrystalline and single-crystal films of iron-substituted strontium titanate, SrðTi 0.65 Fe 0.35 ÞO 3−δ , prepared by pulsed laser deposition, show room-temperature magnetism and Faraday rotation, with the polycrystalline films exhibiting higher saturation magnetization and Faraday rotation. The magnetic properties vary with the oxygen pressure at which the films are grown, showing a maximum at pressures of approximately 4 μ Torr at which the unit-cell volume is largest. The results are discussed in terms of the oxygen stoichiometry and corresponding Fe valence states, the structure and strain state, and the presence of small-volume fractions of metallic Fe in single-crystal films grown at the optimum deposition pressure. Integration of magneto-optical polycrystalline films on an optical-waveguide device demonstrates a nonreciprocal phase shift.

“…In particular, MOKE measurements of Ce∶YIG reveal an increase of a factor of 2 of the Kerr rotation for λ ¼ 406 nm, compared to YIG, and a tenfold increase of the Kerr rotation for λ ¼ 635 nm. This investigation of the MOKE in this material shows that the MOKE is significant for both wavelengths demonstrating the broader applicability of this material for magneto-optic devices, like sensors [38,39], allowing for high resolution magneto-optic imaging. Our magnetic microscopy reveals a strong contrast for the different magnetic domain orientations, highlighting that, in addition to applications, this insulating material provides an excellent research basis for investigation of complex magnetic phenomena like the magneto-optic imaging of magnetostatic spin-wave eigenmodes [24,25] and domain-wall motion due to magnonic spin currents [28,33].…”

“…For YIG and other iron garnets, strain has been found to allow the engineering of the anisotropies [36,37]. However, element substitution such as Ce doping could provide another approach, which has not been investigated so far but is of interest for all spintronic applications, in particular, for magneto-optic sensors [38,39]. Tailoring the anisotropy is key as it allows one to determine the orientation of the device.…”

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.
