Basic microwave properties of magnetic photonic (MPC) and degenerate band edge (DBE) crystals are investigated mathematically and experimentally. Two dimensional and three dimensional models are considered demonstrating the very high sensitivity and field growth associated with these crystals. A major part of the paper deals with the development of realistic anisotropic periodic structures usin...

Major advances in laser technology at LLE have included the demonstration of high-efficiency frequency doubling and tripling of fusion lasers1 and the development of short-pulse, chirped-pulse-amplification (CPA) lasers2 These technologies were combined a few years ago with the demonstration of 75% efficient frequency doubling of 1.6-ps laser pulses on the CPA T~ (table-top terawatt) system at ...

The Lyagkomina occurrence of kyanite amphibolites (the Belomorian Province the Fennoscandian Shield) is confined to an amphibolite boudin among kyanite-garnet-biotite and garnet-biotite gneisses Chupa Sequence. main rock types at are meso- melanocratic garnet-kyanite with large (more than 1 cm in length) kyanite-garnet small kyanite. There also leucocratic garnet-biotite-amphibole-plagioclase r...

From muon spin relaxation spectroscopy experiments, we show that the sharp peak (lambda-type anomaly) detected by specific heat measurements at 54 mK for the ytterbium gallium garnet compound, Yb3Ga5O12, does not correspond to the onset of a magnetic phase transition, but to a pronounced building up of dynamical magnetic pair correlations. Beside the lambda anomaly, a broad hump is observed at ...

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...
