Add to Calendar 4/6/2018 1:00 pm 4/6/2018 America/Chicago Condensed Matter Seminar: "PrP Probing magnons with inelastic light scattering" DESCRIPTION:

Fundamental excitations (e.g. plasmons, excitons, phonons and magnons) determine both the equilibrium and non-equilibrium properties. In this talk, I will discuss our recent work on investigating magnons using Brillouin light scattering technique. In one example, we drive phonon and magnon in yttrium iron garnet out of equilibrium by creating a large temperature gradient. To characterize magnon-phonon coupling strength, we develop a temperature sensing method capable of characterizing phonons and magnons temperatures separately. In another study, we investigated interfacial Dzyaloshinskii–Moriya interaction (DMI) by measuring asymmetric spin wave dispersion in magnetic multiplayers.
