Interaction between quasiparticles of a different nature, such as magnons and phonons in magnetic medium, leads to the mixing their properties formation hybrid states areas intersection individual spectral branches. We recently reported discovery new phenomenon mediated by magnon-phonon interaction: spontaneous bottleneck accumulation magneto-elastic bosons under electromagnetic pumping pure in...
Cerium substituted yttrium iron garnet (Ce:YIG) epitaxial thin films are prepared on a gadolinium gallium (GGG) substrate with pulsed laser deposition. It is observed that the grown GGG(111) exhibit perpendicular magnetic anisotropy (PMA) as compared to GGG(100) substrate. The developed PMA confirmed from magneto-optical Kerr effect, bulk magnetization, and ferromagnetic resonance measurements....
Excitation of magnetization dynamics by pure spin currents has been recently recognized as an enabling mechanism for spintronics and magnonics, which allows implementation of spin-torque devices based on low-damping insulating magnetic materials. Here we report the first spatially-resolved study of the dynamic modes excited by pure spin current in nanometer-thick microscopic insulating Yttrium ...
We report on a comparative study of spin Hall related effects and magnetoresistance in YIG|Pt and YIG|Ta bilayers. These combined measurements allow to estimate the characteristic transport parameters of both Pt and Ta layers juxtaposed to yttrium iron garnet (YIG): the spin mixing conductance G↑↓ at the YIG|normal metal interface, the spin Hall angle SH, and the spin diffusion length λsd in th...
Seven decades after the discovery of collective spin excitations in microwave-irradiated ferromagnets, there has been a rebirth of magnonics. However, magnetic nanodevices will enable smart GHz-to-THz devices at low power consumption only, if such spin waves (magnons) are generated and manipulated on the sub-100 nm scale. Here we show how magnons with a wavelength of a few 10 nm are exploited b...
Faraday rotators that employ the magneto-optic effect are ubiquitous across several optical device categories: including optical isolators, polarization controllers, and spatial light modulators. However, Faraday rotators are notoriously difficult to fabricate at small scales due to the high magnetic field strengths required to generate significant light polarization vector rotations. In this p...
