Linewidth reductions in garnet ferrites

IEE Colloquium on Advances in Passive Microwave Components, 1997
The linewidth of a ferrimagnetic material is a measure of the magnetic loss caused by gyromagnetic resonance of the iron electrons. The authors investigate the effect of substitutions in YIG on properties such as saturation magnetisation, linewidth and Curie temperature.

High efficiency ELID grinding of garnet ferrite

Journal of Materials Processing Technology, 2002
Abstract Hard and brittle materials such as ferrite, optical glass and ceramics have been used in many fields and still gain increasing attention. They are difficult to machine and it is hard to obtain good surface quality. Some workpieces of large batch production have large machining allowances and the machining efficiency is low with the usual ...

On the magnetic phase transition in terbium ferrite-garnet

Solid State Communications, 1978
It is shown that anomalies on the magnetization curves of the samples of terbium ferrite-garnet (Tb3Fe5O12) revealed by Tran Khanh Vien and Dormann [1] are due to the first order spin-reorientation phase transition in iron sublattices. This transition is satisfactorily described by the simple phenomenological theory taking into consideration only ...

Stable spiral domains in ferrite-garnet films

Bulletin of the Russian Academy of Sciences: Physics, 2008
Stable spiral domain structures—spiral domains stabilized by a bubble lattice and lattices of spiral domains—in epitaxial ferrite-garnet films have been experimentally investigated. The thermodynamic approach based on the concept of magnetostatic pressure is applied to explain the behavior of a spiral domain structure with a change in temperature or ...

Optical and Infrared Spectra of the Ferrites and Garnets

Journal of Applied Physics, 1961
A discussion of the variety of applications of spectroscopy to the study of magnetic materials (as restricted to the ferrites and garnets) is presented. Far infrared atomic spectra, infrared vibration spectra, and impurity spectra are discussed as well as the visible and near-visible spectra of the transition metal and rare earth ions.

Domain walls quasistatics in ferrite-garnet films

Journal of Magnetism and Magnetic Materials, 1995
Abstract We propose a criterion for separating domain wall motion into quasistatic and dynamic regimes. The model for potential relief allows the analysis of the domain wall quasistatics using only one method. It is demonstrated that our model makes it possible to obtain the potential relief for every real ferromagnetic film. The method proposed here

Magnetoelectric properties of epitaxial ferrite garnet films

Journal of Magnetism and Magnetic Materials, 2018
Abstract Magnetoelectric properties of ferrite garnets are of great interest due to possibility of electric control of micromagnetic structures at room temperatures promising for applications in advanced technologies. However, the governing mechanisms underlying magnetoelectric coupling and origin of ferroelectricity in these materials remain under ...

Faraday rotation of terbium-yttrium ferrite garnet

IEEE Transactions on Magnetics, 1990
The authors report Faraday rotation (FR) measurements performed on single crystals of terbium-yttrium iron garnets at 1.15- mu m wavelength for three terbium contents (1.98, 1.02, and 0.35) in the temperature range 6-300 K, under magnetic field up to 20 kOe applied along ...

Magnetoelastic coupling constants of the ferrites and garnets

Proceedings of the IEEE, 1965
Magnetoelastic coupling has proven useful in microwave-frequency delay lines and amplifiers. Techniques for measuring the magnetoelastic coupling constants are reviewed here, and some results for the ferrites and garnets are given. The microscopic origin of magnetoelasfic coupling is also discussed.

The infra-red refractive index of garnet ferrites

British Journal of Applied Physics, 1965
The refractive index has been measured by the method of minimum deviation on single crystals of Y3Fe5O12 and Gd1.5Y1.5Fe5O12. The index was found to be 2.168 ± 0.003 at 3.0 μm with a variation of the order of 5% between 1 and 6 μm. It is concluded that the Faraday rotation should vary in sympathy with the index in this region.
