Abstract:

Terahertz (THz) electromagnetic radiation is located between the realms of electronics and optics and has successfully been used to probe and even control numerous low-energy excitations including phonons, excitons and Cooper pairs. Here, we show that THz spectroscopy is also a highly useful tool in the field of ultrafast spinbased electronics (spintronics) and consider the resonant manipulation of the magnetization of an antiferromagnet (through the THz Zeeman torque) and the probing of the tailored transport of spin density from a ferromagnetic into a nonmagnetic metal (through the THz inverse spin Hall effect).
