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

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

Optical Spin Waves

Nano Letters, 2023
Chirality is inherent to a broad range of systems, including in solid-state and wave physics. The precession (chiral motion) of electron spins in magnetic materials, forming spin waves, has various properties and many applications in magnetism and spintronics.

Micro-focused Brillouin light scattering: imaging spin waves at the nanoscale

Frontiers in Physics, 2015
Spin waves constitute an important part of research in the field of magnetization dynamics. Spin waves are the elementary excitations of the spin system in a magnetically ordered material state and magnons are their quasi particles.

Experimental demonstration of a concave grating for spin waves in the Rowland arrangement [PDF]

Scientific Reports, 2021
We experimentally demonstrate the operation of a Rowland-type concave grating for spin waves, with potential application as a microwave spectrometer.

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.

Unidirectional Maxwellian spin waves

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
