Defect structure of rare-earth gallium germanium garnets ...

01/07/2000  The garnet structure (cation distributions overc, a, andd sites; valence states of ions; etc.) was modeled using a semiempirical relation between the lattice parameter and Shannon’s radii of the cations occupying dodecahedral, octahedral, and tetrahedral sites and earlier experimental data. The nature of the defect species present and their concentrations are assessed and the competition ...

Gadolinium Gallium Garnet SpringerLink

Gadolinium gallium garnet (Gd 3 Ga 5 O 12, or GGG) is perhaps the most perfect single crystal material being produced in large quantities in the world today. The achievement of this high state of perfection has been dictated by the rigid requirements of magnetic bubble devices. This paper discusses the, state of the art preparation of single crystal GGG. The sources and nature of the principle ...

Gadolinium-Gallium Garnet - an overview ScienceDirect

Synthetic garnets such as YAG (yttrium aluminum garnet, Y 3 Al 5 O 12), YIG (yttrium iron garnet) and GGG (gadolinium gallium garnet) are of interest for use as substrates for bubble memory and other electronic devices, while natural silicate garnets are of interest because they are the dominant minerals in the transition zone of the earth's mantle and hence may control its rheology [177]. For ...

Gadolinium gallium garnet - Wikipedia

Gadolinium Gallium Garnet (GGG, Gd 3 Ga 5 O 12) is a synthetic crystalline material of the garnet group, with good mechanical, thermal, and optical properties. [further explanation needed] It is typically colorless.It has a cubic lattice, a density of 7.08 g/cm 3 and its Mohs hardness is variously noted as 6.5 and 7.5. Its crystals are produced with the Czochralski method.

Gadolinium Gallium Garnet - RationalWiki

31/01/2020  Gadolinium Gallium Garnet is an urban legend of an ultra dense digital storage medium, information about which can of course be exclusively accessed via the deep web.. The name was likely first coined in in 2011/2012 when the notorious deep web levels info graphic was created. In October 2012 a paste was created which references the real substance Terbium Gallium Garnet.

Herein, we demonstrate a novel calcium gallium germanium garnet (Ca3Ga2Ge3O12) host where lanthanide ions such as Tm(3+)/Yb(3+) and transition metal ions such as Cr(3+) can be easily incorporated through substituting the Ca(2+) and Ga(3+) respectively. This Cr/Yb/Tm:Ca3Ga2Ge3O12 phosphor exhibits both broadband near-infrared long-lasting phosphorescence of Cr(3+) with an

The nature of the chemical bond in garnets - NASA/ADS

The light refraction indexes of a series of rare earth gallium garnets and calcium-gallium-germanium garnet have been measured using the prism method. The nature of the chemical bond in these garnets is analyzed in the context of the Phillips dielectric theory. It is shown that, in terms of ionicity, the degree of covalence in garnet crystals is largely determined by the characteristics of the ...

Segregation in Czochralski grown calcium gallium

Morphology and crystallography of the formation of small segregates in Czochralski grown calcium gallium germanium garnet are studied using TEM and STEM. Based on the observations, the following model has been developed for the formation of these defects. Evaporative loss of Ge from the melt during the crystal growth and the resulting local deviations from stoichiometry lead to random ...
