THz-Radiation Generated from Interfacial Spin-Orbit Coupling

May 18, 2018 - Electromagnetic terahertz (THz) radiation is a versatile tool for a wide variety of sensing technologies ranging from security systems to medical applications.  Commonly, THz radiation is created using photoconductive switches and nonlinear crystals.  Recently, it was shown that optical excitation of fast spin current pulses in magnetic materials may generate strong THz radiation from transverse spin transport phenomena.
