Engineering structured magnetic bits for magnonic holographic memory

open access: yesAIP Advances, 2023
Magnonic holographic memory is a type of memory that uses spin waves for magnetic bit read-in and read-out. Its operation is based on the interaction between magnets and propagating spin waves where the phase and the amplitude of the spin wave are ...

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

open access: yesFrontiers 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.

Boundary Reflections of Rolling Waves in Cubic Anisotropic Material

open access: yesFrontiers in Mechanical Engineering, 2021
Rolling waves have unconventional circular polarizations enabled by the equal-speed propagation of longitudinal and transverse waves in elastic solids. They can transport non-paraxial intrinsic (i.e. spin) mechanical angular momentum in the media.

Reversal of nanomagnets by propagating magnons in ferrimagnetic yttrium iron garnet enabling nonvolatile magnon memory

open access: yesNature Communications, 2023
Spin wave based computing has great promise, offering advantage of low power consumption, aided by the absence of currents and therefore Joule heating.

Generation of spin waves by a train of fs-laser pulses: a novel approach for tuning magnon wavelength

open access: yesScientific Reports, 2017
Currently spin waves are considered for computation and data processing as an alternative to charge currents. Generation of spin waves by ultrashort laser pulses provides several important advances with respect to conventional approaches using microwaves.

Spin-wave turbulence

open access: yesNuclear Physics B - Proceedings Supplements, 1987
Abstract A high resolution study is made of spin-wave dynamics above the Suhl threshold in a sphere of yttrium iron garnet driven by microwave ferromagnetic resonance. In different regions of parameter space observed behavior includes: excitation of a single spatial spin-wave mode at threshold; when two modes are excited, low frequency collective ...
