All-optical generation and time-resolved polarimetry of magnetoacoustic resonances via transient grating spectroscopy

HIGHLIGHTS

  • who: Carrara P. from the , Italy have published the research work: All-Optical Generation and Time-Resolved Polarimetry of Magnetoacoustic Resonances via Transient Grating Spectroscopy, in the Journal: (JOURNAL) of 28/06/2022
  • what: The authors implement a setup to optically generate SAWs also seeding coherent spin waves magnetoelastic coupling in ferromagnetic media. The authors report on SAW-driven ferromagnetic resonance (FMR) experiments performed on polycrystalline Ni thin films in combination with time-resolved Faraday polarimetry which allows extraction of the value of the effective magnetization and of the Gilbert damping. Expanding on that approach . . .
