Gadolinium gallium-garnets

Carnets. Both YAG, yttrium aluminum garnet. YjAIsOi3, and GGG, gadolinium gallium garnet. GdiGa 0,2. have the garnet structure and were used al one time as diamond imitations. These have been supplanted by cubic zirconia. [Pg.708]

The non-volatile bubble memories used for data storage are based on the principle of formation of magnetic domains in thin films grown on a gadolinium gallium garnet crystal substrate. Molecular engineering creates the precise film compositions for optimum performance. [Pg.931]

Yttrium iron garnet (YIG) is used in devices that process microwaves. Growing YIG and LnIG films on perfect crystals obtained from gadolinium gallium garnet (GGG) is involved in ceramics which have technological applications. [Pg.936]

Fluid flow within the melt has a crucial effect on crystal quality. If the crystal is stationary, the dominant convection pattern is upward flow of material at the crucible walls and radial flow inward at the surface (type I). Rapid rotation of crystal causes material to be thrown radially outward at the surface, and opposes the thermal convective flow (type III). These flow patterns are shown in Figure 3. In the intermediate regime, where the two flows are of comparable rates, a more complex surface pattern is observed, labeled type II. The crystal-liquid interface is convex toward the melt in type I flow and planar in type II, a condition that is used for the growth of large crystals of gadolinium gallium garnet ... [Pg.105]

We lower the temperature to just above that point. A substrate slice of single- crystal GGG (gadolinium gallium garnet = GdsGteis O12) is then... [Pg.330]
