We use Brillouin light scattering ~BLS! to study a series of single-crystal Bi-doped yttrium iron garnet Y32xBixFe5O12 ~Bi-YIG! prepared with x5 0, 0.14, 0.36, 0.54, and 0.92. BLS shows that the optimal laser power should be as low as possible, <5 mW. BLS manifests the Bi-concentration dependence of the magnetic and mechanic properties of Bi-YIG. Two bulk magnons are observed. One is the therma...

Multiferroic materials with good magneto-electric coupling are of great interest due to their enormous applications in the field spintronic devices. Magnetoelectric (ME) gallium ferrite is an interesting material its room temperature (RT) piezoelectricity and near RT ferrimagnetism along significant ME (10 −11 s/m at 4.2 K). The work aims increase magnetic transition (T C ) above so that can ha...

Manipulating magnetism by electric current is of great interest for both fundamental and technological reasons. Much effort has been dedicated to spin-orbit torques (SOTs) in metallic structures, while quantitative investigation of analogous phenomena in magnetic insulators remains challenging due to their low electrical conductivity. Here we address this challenge by exploiting the interaction...

GIY-YIG homing endonucleases are modular proteins, with conserved N-terminal catalytic domains connected by linkers to C-terminal DNA-binding domains. I-TevI, the T4 phage GIY-YIG intron endonuclease, functions both in promoting td intron homing, and in acting as a transcriptional autorepressor. Repression is achieved by binding to an operator, which is cleaved at 100-fold reduced efficiency re...

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...

We study spin Hall magnetoresistance (SMR) in Pt/ferrimagnetic insulator Y$_{3}$Fe$_{5}$O$_{12}$ (YIG) bilayers by focusing on crystallinity, magnetization, and interface roughness controlling post-annealing temperatures. The SMR the Pt/YIG grown Si substrate is comparable to that widely used Gd$_{3}$Ga$_{5}$O$_{12}$ substrate, indicating large can be achieved irrespective crystallinity. deduce...

Flexible magnetic materials and devices with basic functional properties are highly desirable for flexible electronic applications in wearable products implantable systems. In this work, a freestanding polycrystalline yttrium iron garnet (YIG) thin film strong magnetism has been synthesized by pulsed laser deposition using water-dissolvable Sr3Al2O6 sacrificial layer, the of resulting was confi...

The combination of yttrium iron garnet (Y3Fe2(FeO4)3, YIG) and ferromagnetic materials or antiferromagnetic has attracted much attention because its potential in applications such as spin pumping. In this study, a high-temperature oxygen-poor environment was used to deposit CoOx top layer on YIG for the observation magnetic modulation. temperature- saturation-field-dependent bias shift hysteres...

Recently, magnons, which are quasiparticles describing the collective motion of spins, were found to undergo Bose-Einstein condensation (BEC) at room temperature in films of Yttrium Iron Garnet (YIG). Unlike other quasiparticle BEC systems, this system has a spectrum with two degenerate minima, which makes it possible for the system to have two condensates in momentum space. Recent Brillouin Li...

The diffraction efficiency (DE) of guided optical waves (GOWs) and the magneto-optic (MO) −3 dB bandwidth are key parameters in MO Bragg cells. To improve the diffraction performance, the MO Stokes interaction between magnetostatic forward volume waves (MSFVWs) and GOWs are studied by use of the coupledmode theory in metal clad yttrium-iron-garnet (YIG) waveguides. Our analysis shows that, by a...
