Resonant inter-mode second harmonic generation by backward spin waves in YIG nano-waveguides
K. O. Nikolaev, S. R. Lake, B. Das Mohapatra +3
We experimentally study nonlinear generation of the second harmonic by backward volume spin waves propagating in microscopic magnonic waveguides fabricated from a low-loss magnetic…
Spatially-extended nonlinear generation of short-wavelength spin waves in YIG nanowaveguides

We experimentally study nonlinear propagation of spin waves in microscopic yttrium iron garnet waveguides, where the dispersion spectrum is engineered to enable efficient four-magn…
Resonant generation of propagating second-harmonic spin waves in nano-waveguides
K. O. Nikolaev, S. R. Lake, G. Schmidt +2
Generation of second-harmonic waves is one of the universal nonlinear phenomena that have found numerous technical applications in many modern technologies, in particular, in photo…
Interplay between nonlinear spectral shift and nonlinear damping of spin waves in ultrathin YIG waveguides
S. R. Lake, B. Divinskiy, G. Schmidt +2
We use the phase-resolved imaging to directly study the nonlinear modification of the wavelength of spin waves propagating in 100-nm thick, in-plane magnetized YIG waveguides. We s…
Evidence for spin current driven Bose-Einstein condensation of magnons
B. Divinskiy, H. Merbouche, V. E. Demidov +9
The quanta of magnetic excitations - magnons - are known for their unique ability to undergo Bose-Einstein condensation at room temperature. This fascinating phenomenon reveals its…
Efficient geometrical control of spin waves in microscopic YIG waveguides

We study experimentally and by micromagnetic simulations the propagation of spin waves in 100-nm thick YIG waveguides, where the width linearly decreases from 2 to 0.5 micrometers…
Dispersionless propagation of ultra-short spin-wave pulses in ultrathin yttrium iron garnet waveguides
B. Divinskiy, H. Merbouche, K. O. Nikolaev +10
We study experimentally the propagation of nanosecond spin-wave pulses in microscopic waveguides made of nanometer-thick yttrium iron garnet films. For these studies, we use micro-…
Spatial separation of degenerate components of magnon Bose-Einstein condensate by using a local acceleration potential
I. V. Borisenko, V. E. Demidov, V. L. Pokrovsky +1
Bose-Einstein condensation (BEC) of magnons is one of few macroscopic quantum phenomena observable at room temperature. Due to competition of the exchange and the magnetic dipole i…
