The electron-phonon coupling in iron-doped yttrium aluminum garnet crystals is studied in the theoretical framework of linear and quadratic coupling. The line shift and line broadening of the zero phonon line of iron centers as a function of temperature between 10 and 150 K is qualitatively and quantitatively explained. The spectroscopic features of the line, deduced from the theory of lattice ...

This paper presents Garnet, a novel spatial hypertext interface to a digital library. Garnet supports both information structuring – via spatial hypertext – and traditional information seeking – via a digital library. A user study of Garnet is reported, together with an analysis of how the organizing work done by users in a spatial hypertext workspace could support later information seeking. Th...

Abstract The trace element contents of zircon can provide unique insights into tectonothermal events, however, interpreting these data and identifying correlations with specific magmatic/metamorphic events be challenging. This limits our ability to construct temporally constrained petrogenetic histories complex metamorphic terranes. Unlocking the information that rare earth (REE) patterns conta...

The effects of exchange coupling on magnetic switching properties of all-garnet multilayer thin film structures are investigated. All-garnet structures are fabricated by sandwiching a magneto-soft material of composition type Bi1.8Lu1.2Fe3.6Al1.4O12 or Bi₃Fe₅O12:Dy₂O₃ in between two magneto-hard garnet material layers of composition type Bi₂Dy₁Fe₄Ga₁O12 or Bi₂Dy₁Fe₄Ga₁O12:Bi₂O₃. The fabricated ...

Rare-earth-doped crystals are excellent hardware for quantum storage of photons. Additional functionality of these materials is added by their waveguiding properties allowing for on-chip photonic networks. However, detection and coherent properties of rare-earth single-spin qubits have not been demonstrated so far. Here we present experimental results on high-fidelity optical initialization, ef...

3.7 Billion year old inclusions inside garnet crystals contain 13C depleted carbonaceous material consistent with biogenic origin. Additional evidence in the form of the other elements of life mainly O, N and P were found to be structural bound to this material by using a new technique, AFM-IR. Here we show additional evidence that support our claim. By overlaying maps generated by the AFM-IR w...
