“…They possess record-high Faraday or Kerr effects simultaneously with low optical losses in parts of the visible and near-infrared regions and are starting to become highly sought after for the development of cost-effective and reliable photonic devices and sensors. Since the 1960s, Bi-substituted MO garnet thin films have been fabricated with different compositional stoichiometries using deposition technologies such as Pulsed Laser Deposition (PLD), Liquid-Phase Epitaxy (LPE), Ion Beam Sputtering (IBS), Reactive Ion Beam Sputtering (RIBS), metal-organic chemical vapor deposition (MOCVD), sol-gel technique, and radio frequency (RF) magnetron sputtering, and using other material synthesis systems [5,[12][13][14][15][16][17][18][19]. All of these physical vapor deposition techniques require complex and multiparameter process optimizations at both the deposition and annealing (crystallization) stages.…”

Abstract:Highly bismuth-substituted iron garnet thin films are prepared on quartz substrates by using a radio frequency (RF) magnetron sputtering technique. We study the factors (process parameters associated with the RF magnetron sputter deposition technique) affecting the magneto-optical (MO) properties of ferrite garnet films of composition Bi 2.1 Dy 0.9 Fe 3.9 Ga 1.1 O 12 . All films show high MO response across the visible range of wavelengths after being annealed. In particular, the effects of substrate stage temperature and rotation rate on the various properties of films are studied. Experimental results reveal that the characteristics of garnet films of this type can be tuned and optimized for use in various magnetic field-driven nanophotonics and integrated optics devices, and that, at a substrate stage rotation rate near 16 revolutions per minute, the MO quality of the developed MO films is the best, in comparison with films deposited at other rotation rates. To the best of our knowledge, this is the first report on the effects of deposition parameters on the properties of garnet films of this stoichiometry.

“…It is now more than 40 years since the giant magneto-optical effects in bismuth-substituted iron garnets (Bi:IG) were reported first in 1969 and used extensively for fabricating various magnetic recording media. But the synthesis efforts aimed at controlling the properties of Bi:IG compounds containing various metal dopants have started back in 1960s, and different methods were used, including Pulsed Laser Deposition (PLD), Liquid Phase Epitaxy (LPE), Ion Beam Sputtering (IBS), Reactive Ion Beam Sputtering (RIBS), Sol-gel process, and RF magnetron sputtering [1][2][3][4][5][6][7][8][9]. Bi:IGs are still considered to be the best magneto-optic (MO) material type among all known semitransparent materials and are therefore of interest for various optical, MO, and other applications.…”

Rare-earth and Bi-substituted iron garnet thin film materials exhibit strong potential for application in various fields of science and frontier optical technologies. Bi-substituted iron garnets possess extraordinary optical and MO properties and are still considered as the best MO functional materials for various emerging integrated optics and photonics applications. However, these MO garnet materials are rarely seen in practical photonics use due to their high optical losses in the visible spectral region. In this paper, we report on the physical properties and magneto-optic behaviour of high-performance RF sputtered highly bismuth-substituted iron garnet and garnet-oxide nanocomposite films of generic composition type (Bi, Dy/Lu)3(Fe, Ga/Al)5O12. Our newly synthesized garnet materials form high-quality nanocrystalline thin film layers which demonstrate excellent optical and MO properties suitable for a wide range of applications in integrated optics and photonics.
