Abstract

We have synthesized Bi₃Fe₄Ga₁O ₁₂ (BIGG) films on Gd₃Ga₅O₁₂ and Gd₃(ScGa)₅O₁₂ substrates by a pulsed laser deposition technique. X-ray diffraction and rocking curve analyses confirm the epitaxial quality of the films with a lattice constant close to 12.61 ± 0.01 Å. Compared with that of a bismuth iron garnet Bi₃Fe ₅O₁₂ (BIG) film, the bandwidth of the BIGG transmittance (T) spectrum is extended and its left edge shifted down in wavelength by approximately 50 nm. This enables its Faraday rotation θ_F and switching speed to be tested at a wavelength of 532 nm. While BIGG film has a Faraday rotation angle slightly less than that of BIG film, its magnetooptical figure of merit, 2|θ_Fd|/-ln(T%), is greatly improved to a typical value ∼1.8 times larger than that of the BIG film. Further, the high-speed pulse response time of the BIGG film reaches 2.4 ns with a 1 mm aperture size at the wavelength of 532 nm.
