Reconfigurable atom chip on a transparent ferrite-garnet film

The European Physical Journal D, 2005
We introduce a new choice of material for the creation of microscopic magnetic potentials for the trapping and guiding of ultracold neutral atoms. The potentials are created above a ferrimagnetic, transparent (BiYTmGd)3(FeGa)5O12 film by patterning the magnetic-domain structure in the film with a magneto-optical recording method.

Anomalies of magnetooptical diffraction in ferrite-garnet films

Russian Physics Journal, 1997
Experimental magnetooptical diffraction spectra produced by the band domain sructure in an epitaxial ferrite-garnet film are described. Asymmetry of the optical field in symmetric maxima is observed when a laser beam is normally incident on the sample.

Spontaneous Magnetization of Some Garnet Ferrites and the Aluminum Substituted Garnet Ferrites

Journal of Applied Physics, 1958
Magnetic properties of 5Fe2O3·3M2O3 where M represents Gd-Tb-Dy-Ho-Er-Tm-Yb-Lu-Y-Sm-Eu are reported. The results are interpreted using Néel's molecular field model. A study of the Al substituted gadolinium garnets shows a preference for Al ions to occupy d sites.

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 ...

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.

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.

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 ...

A mixed domain structure in ferrite-garnet films

Journal of Experimental and Theoretical Physics, 2002
A stable static mixed domain structure consisting of strip domains and a cylindrical magnetic domain (CMD) is obtained in (Bi0.7Lu0.3)3 (Fe0.8Ga0.2)5 O12 ferrite-garnet films. An analytic theory of the mixed domain structure is constructed. An analytic solution is obtained for the shape of a distorted strip domain, which is in good agreement with ...
