A theoretical model for how Bloch walls occurring in in-plane magnetized ferrite garnet films can serve as efficient magnetic micromanipulators is presented. As an example, the walls' interaction with Abrikosov vortices in a superconductor in close contact with a garnet film is analyzed within the London approximation. The model explains how vortices are attracted to such walls, and excellent q...

The formation of atoll garnet in the Ardara aureole, NW Ireland, is discussed using the textural, chemical and Electron Backscatter Diffraction (EBSD) data. Textural evidence suggests the possibility of incipient of garnet replacement from the core. In addition, the presence of staurolite and andalusite in the core of small atoll garnets as well as the occurrence of sillimanite in the core of l...

Glaucophane-bearing rocks — indicators of high-pressure metamorphism were earlier found in the Polar Urals Neoproterozoic deposits Nyarovey series, northern part Marunkeu eclogite-amphibolite-gneiss complex, and foot ultramafic massifs Main Ural Fault (MUF) zone. We have discovered western endocontact Kharbey amphibolite-gneiss where they are represented by garnet-glaucophane, garnet-glaucophan...

Passive Q switching of solid-state lasers is usually accomplished with organic dyes or color centers as the saturable absorber. Dyes, however, have poor thermal stability and tend to degrade rapidly. To operate in cw-pumped lasers, dyes require a circulation system. Color centers, such as the color-center LiF crystal, -3 exhibit a fading phenomenon that may limit the period of reliable operatio...

We have investigated the Faraday rotation of in-plane magnetized bismuth-substituted ferrite garnet films grown by liquid phase epitaxy on (100) oriented gadolinium gallium garnet substrates. The Faraday spectra were measured for photon energies between 1.7-2.6 eV. To interprete the spectra, we use a model based on two electric dipole transitions, one tetrahedral and one octahedral. Furthermore...
