“…Bisubstituted iron garnet thin film materials are one of the best transparent MO materials possessing the giant MO properties. Since 1960 Bi:IGs' of different compositions containing different metal dopants have been produced and their properties have been studied extensively to realise their potential in various new and existing technologies [1][2][3][4][5][6][7][8][9]. Bi:IGs are still considered to be the best materials for use in non-reciprocal optical components, magnetic recording, magnetic field sensing and imaging as well as for applications in magnetically-tunable photonic crystal devices.…”

“…Multiple variations in the material properties of garnets are required for different applications in integrated optics and in photonics, and these can be engineered by adjusting the material composition. This work is devoted to the synthesis and characterisation of highly Bi-substituted lutetium iron garnet thin films of composition type (BiLu) 3 (FeAl) 5 O 12 featuring a strong in-plane magnetization component and magnetically-soft switching behavior. Previous work on the synthesis of monocrystalline films of a similar composition type using a different technology has been reported by Adachi et al in 2002 [22].…”

“…Previous work on the synthesis of monocrystalline films of a similar composition type using a different technology has been reported by Adachi et al in 2002 [22]. They reported on the preparation of (BiLu) 3 (FeGa) 5 O 12 garnet films by the liquid-phase epitaxy (LPE) technique, and their monocrystalline layers were also postannealed at high temperatures to obtain the in-plane magnetic anisotropy. The resulting inplane magnetized thin-film materials possessed the properties suitable for magnetic flux visualization in high-T c superconductors.…”

“…The magneto-optic sensors used by PRi consist of a thin film of bismuth-doped iron garnet (Bi,Tm)3(Fe,Oa)5012 grown on a 3-inch diameter, 0.020 inch-thick substrate of gadolinium gallium garnet (000) [14][15][16]. These films exhibit three physical properties that are crucial for a practical magneto-optic/eddy current imaging instrument.…”

Review of Progress in Quantitative Nondestructive Evaluation

The rate of production of new aircraft, as well as the availability of funds to purchase them, are limited. As a consequence of these two factors, only a small percentage of the many thousands of aging aircraft in existence today (both civilian and military), will be replaced by new aircraft in the foreseeable future. Because replacement is not an option in many cases, the only practical way to maintain operations is to extend the useful service lifetimes of these aircraft by means of proper maintenance, repairs and upgrades [1]. An important component of proper maintenance is periodic inspection for subsurface corrosion and fatigue cracking in airframes.Nondestructive inspection (NDI) methods used for this purpose [2] include, among others, visual examination, eddy current inspection, x-ray and ultrasonic inspection, and more recently, neutron radiography. Although each of these inspection methods can successfully detect subsurface corrosion and cracks, they all have limitations.Conventional visual examinations can detect large surface-breaking cracks or extensive corrosion-induced "bulging" or "pillowing" of visible surfaces. However, this method generally cannot detect small surface-breaking cracks or tiny surface displacements associated with subsurface cracks or areas of corrosion where no pillowing occurs. Furthermore, even in areas of significant pillowing, other reliable easy-to-use NDI methods must still be used to verify the existence of corrosion.Conventional eddy current and ultrasonic methods are essentially point-contact inspection methods, which significantly limits inspection speed and makes these methods very tedious. Through-transmission x-ray and neutron radiography inspections have limited applicability because the source and receiver of radiation must be on opposite sides of the inspection surface. A notable exception to this constraint is the successful, but relatively expensive, x-ray backscatter technique.

“…Bismuth (Bi)-substituted magneto-optical (MO) garnet materials are very attractive for use in various technological applications such as magnetic memory, magnetoplasmonic devices, magneto-optic sensors, lightwave polarization controllers, and MO spatial or temporal light modulators [1][2][3][4][5][6][7][8][9][10][11]. 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.…”

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.
