Imaging and phase-locking of non-linear spin waves [PDF]

Nature Communications, 2022
Many proposed spin-wave based devices make use of non-linear behaviour of spin-waves. Here, Dreyer et al show the emergence of non-linear spin waves oscillating at half-integer harmonics in the strong modulation regime. By applying super-Nyquist sampling

Giant nonlinear self-phase modulation of large-amplitude spin waves in microscopic YIG waveguides [PDF]

Scientific Reports, 2022
Nonlinear self-phase modulation is a universal phenomenon responsible, for example, for the formation of propagating dynamic solitons. It has been reported for waves of different physical nature. However its direct experimental observation for spin waves

Snell’s Law for Spin Waves [PDF]

Physical Review Letters, 2016
We report the experimental observation of Snell's law for magneto-static spin waves in thin ferromagnetic Permalloy films by imaging incident, refracted and reflected waves. We use a thickness step as the interface between two media with different dispersion relation. Since the dispersion relation for magneto-static waves in thin ferromagnetic films is

Resonant generation of propagating second-harmonic spin waves in nano-waveguides [PDF]

Nature Communications
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 photonics.

True amplification of spin waves in magnonic nano-waveguides [PDF]

Nature Communications
Magnonic nano-devices exploit magnons - quanta of spin waves - to transmit and process information within a single integrated platform that has the potential to outperform traditional semiconductor-based electronics.

Detection of Short-Waved Spin Waves in Individual Microscopic Spin-Wave Waveguides Using the Inverse Spin Hall Effect [PDF]

Nano Letters, 2017
The miniaturization of complementary metal-oxide-semiconductor (CMOS) devices becomes increasingly difficult due to fundamental limitations and the increase of leakage currents. Large research efforts are devoted to find alternative concepts that allow for a larger data-density and lower power consumption than conventional semiconductor approaches ...

Time Refraction of Spin Waves [PDF]

Physical Review Letters, 2021
We present an experimental study of time refraction of spin waves propagating in microscopic waveguides under the influence of time-varying magnetic fields. Using space- and time-resolved Brillouin light scattering microscopy, we demonstrate that the broken translational symmetry along the time coordinate can be used to in- or decrease the energy of ...
