Major element diffusion in garnet and the exsolution of majoritic garnet from aluminous enstatite in Earth's Upper Mantle
… a high pressure polymorph of enstatite with the garnet structure. The amount of enstatite that can be dissolved in garnet as a majorite component increases significantly with pressure, and therefore, majoritic garnet is thought to be a major constituent of the Earth's transition zone. The …

Properties of off stoichiometric yttrium iron garnet
… shows that high-quality epitaxial garnet phase is formed on GGG substrates. However, RSM results show that the off-stoichiometric YIG film on (111) GGG substrates can remain fully strained in plane with thickness from 23 nm to 74 nm; while the samples on (001) GGG substrates show …

Microstructural Analysis of Garnet-Heavy Metal Heterostructures
Rare earth iron garnets (REIGs) are a class of ferrimagnetic insulators desirable for their tunable magnetic properties. Saturation magnetization, perpendicular magnetic anisotropy (PMA), coercivity, and Gilbert damping are just a few characteristics that can be altered via elemental substitution …

Laser spectroscopy of color centers in yttrium aluminum garnet
Nd:YAG lasers have become ubiquitous as tools for spectroscopy, materials processing, and medical care. It is well known by crystal growers that lattice defects in Nd:YAG can stifle laser efficiency, but to date very little has been done to isolate and characterize individual YAG defects. Knowing …

Pulsed Laser Deposited Iron Garnet Thin Films for Spintronics
… memories and demonstrate growth of iron garnet superlattices with layering at a sub unit cell scale. Iron garnet films are suitable for next generation spintronic memories because of their low Gilbert damping and their growth with perpendicular magnetic anisotropy (PMA) which promote fast …

Iron Garnet Thin Films for Integrated Photonics and Spintronics
… and ultra-fast spintronic memory. Iron garnet thin films are uniquely suited for both applications as they have: 1) strong magneto-optic (MO) response and low optical absorption at communication wavelengths making them enablers for nonreciprocal devices essential in photonic integrated …

Nanometer-thick yttrium iron garnet film development and spintronics-related study
… a considerable interest in using yttrium iron garnet (Y3Fe5O12, YIG) materials for magnetic insulator-based spintronics studies. This interest derives from the fact that YIG materials have very low intrinsic damping. The development of YIG-based spintronics demands YIG films that have a …

The Cause of Anisotropy in Symmetrically Cubic Almandine and Spessartine Garnet
The origin of optical anisotropy in garnet has been an unanswered question for over a century. Previous studies have hypothesized birefringence to be related to large scale twinning, the inclusion of OH groups within the tetrahedral site, cation ordering of the dodecahedral and octahedral sites and …
