Yttrium iron garnet powders have been synthesized by chemical coprecipitation using two different precursors, nitrates and chlorides, and by an oxides mixture route. It is shown that depending on the precursors and synthesis conditions used pure yttrium iron garnet powders can be obtained with a mono or multidomain magnetic behaviour. The yttrium iron garnet crystalline structure, as studied by...

Colloidal nanodispersion of Iron Yttrium Garnet has been preparedbymixing the two ternary mixture of Triton X-100 (surfactant), n-heptane and aqueous solution that differing only in the aqueous phase.Ethanolwas added as cosurfactant and mixed them by ultrasound bath. By mixing these twomicroemulsions, Iron Yttrium garnet (Y3 Fe5 O12) nanodispersionwas obtained. Solids were settled by centrifuge...

The optical and magneto-optical activities of yttrium iron garnet are shown to depend on the sintering stage. Low density yttrium iron garnet presents a lower optical activity than the high density garnet. The magneto-optical activity decreases at energies in which the optical transitions are associated to crystal field, indicating a relationship between the optical activity and the distortion ...

This is our initial response towards fabricating a magnetic filled polymer composite samples potentially used as electromagnetic waves detector. Samples of lanthanum yttrium iron garnet Y3.0-XLaXFe5O12 (where x = 0, 0.5 ,1.0, 1.5 , 2.0, 2.5, 3.0 ) were synthesized by conventional solid state technique. We used simple casting technique to fabricate the Y3.0XLaXFe5O12-PVA composite. The samples w...

A summary of our recent progress in the growth and characterization of magnetic and magnetooptic garnet heterostructures is presented in this paper. The similarity in crystal chemistry and lattice parameters among the various garnets (yttrium iron garnet, bismuth iron garnet, etc.) is utilized to create artificially layered heterostructures and superlattices. Rare earth (especially Eu) substitu...

The possibility of intense radiation short-wave exchange spin waves excited in a thin transition layer at the internal boundary bilayer ferrite-ferrite structure is shown. Modelling processes has been exemplified by tangentially magnetized film ferric-yttrium garnet. It was found that one-way character. were radiated into with decreased magnetization. Their group velocities an order magnitude l...

Spin-momentum locking in protected surface states enables efficient electrical detection of magnon decay at a magnetic-insulator/topological-insulator heterojunction. Here we demonstrate this property using the spin Seebeck effect (SSE), that is, measuring the transverse thermoelectric response to a temperature gradient across a thin film of yttrium iron garnet, an insulating ferrimagnet, and f...

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...
