Abstract

The recent invention of spintronic THz emitters has attracted a lot of attention due to their high power, broadband emission, and easy fabrication. They commonly consist of nanometer-thin bilayers of a magnetic (M) and a nonmagnetic (NM) metal film and rely on the inverse spin Hall effect. In my talk, I will present our recent results on bilayer M/NM spintronic emitters based on magnetic alloys, such as GdFe or CoFe, and Pt as the NM layer. Furthermore, functional multilayer spintronic THz emitter systems, which can be conveniently switched on and off, will be presented.
