The appearance of spontaneous coherence is a fundamental feature Bose-Einstein condensate and an essential requirement for possible applications the condensates data processing quantum computing. In case magnon in magnetic crystal, such computing can be performed even at room temperature. We study process formation coherent by direct detection microwave radiation emitted magnons parametrically ...

In this Letter, we present experimental data that demonstrate a spin wave interference detection using an inverse Hall effect (ISHE). Two coherent waves are excited in yttrium-iron garnet waveguide by continuous microwave signals. The initial phase difference between the is controlled external shifter. ISHE voltage detected at distance of 2 and 4 mm away from generating antennas attached Pt lay...

In ferromagnets, domain patterns can be controlled globally using magnetic fields or spin-polarized currents. contrast, the local control of magnetization on nanometer length scale remains challenging. Here, we demonstrate how in a Tm-doped yttrium iron garnet (Tm:YIG) thin film with perpendicular anisotropy permanently and locally imprinted by high intensity photon pulses hard x-ray transient ...

We demonstrate the influence of damping and field-like torques in magnon-photon coupling process by classically integrating generalized Landau-Lifshitz-Gilbert equation with RLC which a phase correlation between dynamic magnetization microwave current through combined Amp\`ere Faraday effects are considered. show that gap two hybridized modes can be controlled samples parameter order $10^{-3}$ ...
