Abstract

We report on narrow band THz emission from ferrimagnetic Mn3-xGa nanofilms based. The emission originates from coherently excited spin precession. The central frequency of the emitted radiation is determined by the anisotropy field, while the bandwidth relates to Gilbert damping. It is shown how THz emission can be used for the characterization dynamical properties of ultra-thin magnetic films. We furthermore discuss the potential of these types of films as efficient on-chip spintronic THz emitter.
