In this study a comprehensive theory is developed for hybrid cavity magnonics system consisting of microwave strongly coupled to spin excitations or magnons in single-crystal yttrium iron garnet (YIG) sample with the exhibiting nonlinear Kerr effect caused by magnetocrystalline anisotropy YIG. The dynamics analysed Hamilton Langevin formulation and it shown that magnon frequency shift due nonli...

Raising the thermoelectric voltage in spin generators is an important subject. We investigated substitution of bismuth for yttrium to increase pumping at paramagnetic metal and ferrimagnetic insulator (PM/FMI) interface, tested bismuth-substituted iron garnet films grown by liquid phase epitaxy. Epitaxial Bi-substituted exhibit large growth-induced magnetic anisotropy perpendicular film surface...

We have demonstrated the capabilities of scanning microwave microscopy (SMM) technique for measuring ferromagnetic resonance (FMR) spectra in nanometric areas magnetic samples. The is evaluated using three different samples, including a yttrium iron garnet (YIG) polycrystalline bulk sample and thick YIG film grown by liquid phase epitaxy (LPE). Patterned permalloy (Py) micromagnetic dots been c...

In this review we introduce computer modelling and simulation techniques which are used for ferrimagnetic materials. We focus on models where thermal effects accounted for, atomistic spin dynamics finite temperature macrospin approaches. survey the literature of two most commonly modelled ferrimagnets in field spintronics--the amorphous alloy GdFeCo magnetic insulator yttrium iron garnet. look ...

The temperature and yttrium-iron-garnet (YIG) thickness dependences of the spin Peltier effect (SPE) have been investigated using a Pt/YIG junction system at temperatures ranging from room to Curie YIG by lock-in thermography method. By analyzing dependence an exponential decay model, characteristic length SPE in is estimated be 0.9 $\mu$m near almost constant even temperature. high-temperature...
