Single crystals of pure and A1 and Zn Ti substituted X Fe1201g Hexaferrite (X = Sr or Ba) have been grown from different solvents by spontaneous nucleation growth method. Strong improvement in crystal size was obtained using Naz0 Fez03 flux. Ferrimagnetic resonance measurements (FMR) versus frequency and temperature were made in the millimeter wavelength range. The contribution of the intrinsic...

The issue of magnetic orientation transitions in thin lms combines interesting physics and importance for applications. We study the magnetic transition and phase diagram of a 0.1 m thick (YLaGd)3(FeGa)5O12 lms grown on GGG substrate by liquid phase epitaxy. Observed transitions are compared with those in BiGa:TmIG thin lms, studied in previous work by one of the authors. A general picture of o...

The spectrum of spin waves (SW) tangentially magnetized films yttrium iron garnet (YIG) with a surface metastructure in the form gratings etched grooves period close to film thickness d (~ d) has been experimentally and numerically studied. It found that signal reflected from microstrip transducer width w>> d, located on YIG contains absorption lines associated excitation SW metas...

The growth of iron-yttrium garnet Y3Fe5O12 (YIG) films with 1...15 μm thicknesses on single-crystal substrates gallium-gadolinium Gd3Ga5O12 (GGG) was carried out using the method liquid phase epitaxy (LPE). influence composition and mass charge, temperature regimes, rates movement substrate rotation parameters were studied. layered structure caused by heterogeneity chemical in film thickness de...

We propose an effective approach for creating robust nonreciprocity of high-order sidebands, including the first-, second- and third-order at microwave frequencies. This relies on magnon Kerr nonlinearity in a cavity magnonics system composed two cavities one yttrium iron garnet (YIG) sphere. By manipulating driving power applied YIG frequency detuning between mode field, can be strengthened, t...

T4 contains two groups of genes with similarity to homing endonucleases, the seg-genes (similarity to endonucleases encoded by group I introns) containing GIY-YIG motifs and the mob-genes (similarity to mobile endonucleases) containing H-N-H motifs. The four seg-genes characterized to date encode homing endonucleases with cleavage sites close to their respective gene loci while none of the mob-...

We report that Joule heating can be used to enhance the interfacial spin conductivity between a metal and an oxide. observe local annealing of interface at about 550 K, when injecting large current densities (>1012A/m2) into pristine 7 nm thick Pt nanostrip evaporated on top yttrium iron garnet (YIG), improve effective transmission up factor 3. This result is particular interest interfac...
