Minerals recovered from the deep mantle provide a rare glimpse into deep Earth processes. We report the first discovery of ferric iron-rich majoritic garnet found as inclusions in a host garnet within an eclogite xenolith originating in the deep mantle. The composition of the host garnet indicates an ultrahigh-pressure metamorphic origin, probably at a depth of ~200 km. More importantly, the fe...

In this work, preparation and crystallization of yttrium iron garnet Y3Fe5O12 super-paramagnetic nanoparticle by aqueous sol–gel processes and its application as an effective nano catalyst for esterification and etherification reactions in short reaction time and in high isolated yields. Then this catalist was used for the synthesis of Dihydropyrimidin derivatives is described. The catalyst was...

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 ...

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...

We report on the fabrication and characterization of a novel magnetophotonic structure designed as iron garnet based magneto-optical nanoresonator cavity constrained by two noble metal mirrors. Since the iron garnet layer requires annealing at high temperatures, the fabrication process can be rather challenging. Special approaches for the protection of metal layers against oxidation and morphol...

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...

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...
