Abstract:
Acoustically mediated spintronic THz emitters in which sound waves, rather than direct laser pulses, give rise to a spin current in a magnetic material via magnetoelastic coupling are provided. The THz emitters include a metal layer that acts as a light-to-acoustic transducer. Also provided are THz time-domain spectrometers (THz-TDSs) that incorporate the THz emitters.
