      abstract     = {Terahertz electromagnetic radiation is extremely useful for
                      numerous applications, including imaging and spectroscopy.
                      It is thus highly desirable to have an efficient table-top
                      emitter covering the 1–30 THz window that is driven by a
                      low-cost, low-power femtosecond laser oscillator. So far,
                      all solid-state emitters solely exploit physics related to
                      the electron charge and deliver emission spectra with
                      substantial gaps. Here, we take advantage of the electron
                      spin to realize a conceptually new terahertz source that
                      relies on three tailored fundamental spintronic and photonic
                      phenomena in magnetic metal multilayers: ultrafast
                      photoinduced spin currents, the inverse spin-Hall effect and
                      a broadband Fabry–Pérot resonance. Guided by an
                      analytical model, this spintronic route offers unique
                      possibilities for systematic optimization. We find that a
                      5.8-nm-thick W/CoFeB/Pt trilayer generates ultrashort pulses
                      fully covering the 1–30 THz range. Our novel source
                      outperforms laser-oscillator-driven emitters such as
                      ZnTe(110) crystals in terms of bandwidth, terahertz field
                      amplitude, flexibility, scalability and cost.},
