Magnon transistor for all-magnon data processing
TLDR
It is demonstrated that the density of magnons flowing from the transistor’s source to its drain can be decreased three orders of magnitude by the injection of Magnon–magnon interactions into the transistor's gate.Abstract:
An attractive direction in next-generation information processing is the development of systems employing particles or quasiparticles other than electrons--ideally with low dissipation--as information carriers. One such candidate is the magnon: the quasiparticle associated with the eigen-excitations of magnetic materials known as spin waves. The realization of single-chip all-magnon information systems demands the development of circuits in which magnon currents can be manipulated by magnons themselves. Using a magnonic crystal--an artificial magnetic material--to enhance nonlinear magnon-magnon interactions, we have succeeded in the realization of magnon-by-magnon control, and the development of a magnon transistor. We present a proof of concept three-terminal device fabricated from an electrically insulating magnetic material. We demonstrate that the density of magnons flowing from the transistor's source to its drain can be decreased three orders of magnitude by the injection of magnons into the transistor's gate.read more

Micro-focused Brillouin light scattering: imaging spin waves at the nanoscale
TL;DR: The optical method of Brillouin light scattering (BLS) spectroscopy is a well established tool for the characterization of spin waves as discussed by the authors, which is the inelastic scattering of light from spin waves and confers several benefits: the ability to map the spin wave intensity distribution with high sensitivity as well as the potential to simultaneously measure the frequency and the wave vector and, therefore, the dispersion properties.
