Abstract
Acoustically mediated spintronic THz emitters based on a stacked, multilayered heterostructure that includes a light-to-acoustic transducer layer, a thermal insulation layer, and a magnetic layer are provided. In the emitters, fast acoustic pulses give rise to long-distance propagation of THz exchange spin waves in a magnetic film. Also provided are THz time-domain spectrometers (THz-TDSs) that incorporate the THz emitters.
