“…2͒ in agreement with previous reports. 4,8 In 1983 n →3d nϪ1 4s orbital promotion transitions. 8 However, these transitions are parity and partly spin forbidden and can, therefore, not account for the relatively large oscillator strength (10 Ϫ3 ) of the transitions observed in these ferrites.…”

A reexamination of the magneto-optical ͑MO͒ spectra of Li 0. Al x 3ϩ Fe 2Ϫx 3ϩ O 4 ͑xϭ0, 0.1, 0.6, and 1͒ and rigorously fitting both the diagonal and the off-diagonal elements of the dielectric tensor with one set of transitions which was consistent for all degrees of Al 3ϩ substitution. Thus, in these ferrites a consistent assignment of all the major transitions in the 2.0 to 5.0 eV energy range to either IVCT or ISCT transitions is made.

“…1 (b) shows transmittance and Faraday rotation spectra of the sample. One can see two attenuations: a strong attenuation below 550 nm is addressed to the s-d charge transfer transition of Bi:YIG 1,2) and another attenuation is LSPR band with the minimum at 750 nm. However, Faraday rotation spectrum showed no enhancement at the wavelength of the LSPR band.…”

“…Bismuth-substituted yttrium iron garnet (Bi:YIG) 1,2) is a well-known magneto optical (MO) material for visible and infrared light regions. However, the MO response of thin Bi:YIG film, which can be useful for compact optical devices, is not that large.…”

Magneto-optical plasmonic Bi:YIG composite films with Ag and Au-Ag alloy particles

To obtain enhancement and wavelength tuning of the magneto-optical (MO) response associated with the localized surface plasmon resonance (LSPR), bismuth-substituted yttrium iron garnet (Bi:YIG) composite films with Ag particles and Au-Ag alloy particles were studied. The Bi:YIG composite film with Ag particles did not show any enhancement of Faraday rotation. On the contrary, the Bi:YIG composite films with Au-Ag particles exhibited the enhancement of the MO response for different wavelengths of LSPR. We observed the enhanced Faraday rotation for the Bi:YIG/Au-Ag composite films with volume ratios of Ag up to 0.6. In addition, when changing the volume ratio of Ag, the peak of rotation shifted to short wavelengths. Disappearance of enhancement for the Bi:YIG/Ag composite film can be addressed to modifying the interfacial medium between the MO host and Ag. Since chemically active Ag particles can form nonmagnetic Ag compound shells separating Bi:YIG and the plasmonic subsystem, the LSPR of Ag particles did not affect the MO response. The Au-Ag alloy particles were chemically stable in the Bi:YIG/Au-Ag composite films.

“…After irradiation, the irradiated area turned to brown, which stems from broad absorption peaks at around 430 and 620 nm. These absorptions can be attributed to the hole-trap centers, e.g., HC 1 and HC 2 at nonbridging oxigens. The HC 1 and HC 2 are the holes trapped at the nonbridging oxygen in the SiO 4 polyhedron with two and three nonbridging oxygen, respectively.…”

“…Magneto-optical properties provide detailed physical information on the electronic and spin structure of materials, 1) and can be enhanced by the plasmonically excited electric field that arises in the interfacial region between the metallic and magnetic NPs. The feature of nanocomposite materials lies in the high flexibility and controllability of their composition compared with singlephase materials, such as ferromagnetic metal alloys.…”

This review focuses on the enhancement of the magneto-optical responses in transparent Fe-oxide-and metal-doped glasses processed with an infrared femtosecond (fs) laser, with an emphasis on the author's works. Femtosecond-laser irradiation and subsequent annealing induces the crystallization of nanoparticle composites consisting of ferrimangetic fe oxides and plasmonic metals, leading to the enhancement of magnetization, optical absorption and magnetooptical faraday rotation angles. By the use of the advantage of the fs-laser processing, novel applications, such as micro-sized optical isolator and miniaturized magnetic field sensors, can be developed.
