Relative compressibilities of five silicate garnets were determined by single-crystal x-ray diffraction on crystals grouped in the same high-pressure mount. The specimens include a natural pyrope [(Mgz.84Feo.IOCao,o6) AI2Si30d, and four synthetic specimens with octahedrally-coordinated silicon: majorite [Mg3(MgSi)Si30 d, calcium-bearing majorite [(Cao.49Mg2.sl)(MgSi)Si30d, sodium majorite [(NaI...

This review article summarizes the recent achievements in stabilization of the metastable lattice of gadolinium aluminate garnet (Gd3Al5O12, GAG) and the related developments of advanced optical materials, including down-conversion phosphors, up-conversion phosphors, transparent ceramics, and single crystals. Whenever possible, the materials are compared with their better known YAG and LuAG cou...

We report the epitaxial growth of high-quality μm-thick yttrium iron garnet (YIG) films on yttrium aluminium garnet (YAG) substrates by pulsed laser deposition (PLD). The effects of substrate temperature and oxygen pressure on composition, crystallinity, optical transmission and ferromagnetic resonance (FMR) linewidth have been investigated. An FMR linewidth as low as 1.75 mT at 6 GHz was achie...

We report a technique to realize reconfigurable colloidal crystals by using the controlled motion of particle defects above an externally modulated magnetic substrate. The transport of particles is induced by applying a uniform rotating magnetic field to a ferrite garnet film characterized by a periodic lattice of magnetic bubbles. For filling factor larger than one colloid per bubble domain, t...

Recrystallization Effects In article number 2212853, Peng Liu, Miguel L. Crespillo, Eva Zarkadoula, and co-workers demonstrate the track damage formation recrystallization effects in garnet crystals under intense electronic excitation, attributed to key role of thermal parameters cation radius ratio. The irradiation-induced nanostructures enable significant bandgap regulation defect-related lum...
