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

Unidirectional Maxwellian spin waves [PDF]

Nanophotonics, 2019
In this article, we develop a unified perspective of unidirectional topological edge waves in nonreciprocal media. We focus on the inherent role of photonic spin in nonreciprocal gyroelectric media, i.e. magnetized metals or magnetized insulators. Due to

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.

Raman fingerprint of two terahertz spin wave branches in a two-dimensional honeycomb Ising ferromagnet

Nature Communications, 2018
Characteristics of spin waves in recently discovered two-dimensional (2D) Ising ferromagnets are still lacking. Here, Jin and Kim et al. report Raman resonance evidence of two sets of surface spin waves in the 2D honeycomb ferromagnet CrI3.

Evanescent Electron Wave Spin

Entropy, 2023
We demonstrate that an evanescent wave spin exists outside a finite quantum well by solving the Dirac equation in a finite cylindrical quantum well. The analytical analysis validates the wavefunction inside an infinite quantum well but recovers a non-zero evanescent wave outside the well.
