“…They are employed as an optical isolator to provide a large Faraday effect in an absorption-free region. 27 These garnets have been highly investigated for magnetic bubble memory 28 because magnetic domains can be manipulated by an external magnetic field. In rapidly progressing spintronics studies, yttrium iron garnets (YIG) are widely used to pump a spin current into contacting metal by the ferromagnetic resonance of YIG.…”

We investigated the optical and magnetic properties of a transparent magnetic garnet with a particular focus on its applications to atomic physics experiments. The garnet film used in this study was a magnetically soft material that was originally designed for a Faraday rotator at optical communication wavelengths in the near infrared region. The film had a thickness of 2.1 μm and a small optical loss at a wavelength of λ=780 nm resonant with Rb atoms. The Faraday effect was also small and, thus, barely affected the polarization of light at λ=780 nm. In contrast, large Faraday rotation angles at shorter wavelengths enabled us to visualize magnetic domains, which were perpendicularly magnetized in alternate directions with a period of 3.6 μm. We confirmed the generation of an evanescent wave on the garnet film, which can be used for the optical observation and manipulation of atoms on the surface of the film. Finally, we demonstrated a magnetic mirror for laser-cooled Rb atoms using the garnet film.

“…They allow to study the problems of resonance and nonlinear magnetization dynamics [1][2][3][4][5][6]. The following two classes of the films are mostly used: polycrystalline films with uniaxial magnetic anisotropy and single-crystal films with cubic magnetic anisotropy.…”

“…So far, many theoretical and experimental studies on waveguide type non-reciprocal devices or switches have been made in the last decade [1,[15][16][17][18][19][20][21][22][23][24]. In these devices magneto-optical power conversion between TE (transverse electric) and TM (transverse magnetic) modes plays a crucial role.…”

“…As for magneto-optical devices, nonreciprocal devices such as isolators and circulators are indispensable to prevent unstable laser oscillation due to the backward beam and to split the forward and backward beams [1].…”
