报告摘要

THz radiation falls between infrared and microwave radiation in the electromagnetic spectrum and can be used for a different types of material characterization. Here, I will discuss (1) Using ultrafast terahertz spectroscopy on a GMR spin-valve, we are able to directly determine the fundamental parameters of magneto-transport – spin-dependent densities and momentum scattering times of conduction electrons in a ferromagnetic metal. (2) Using terahertz emission spectroscopy, we probe the elementary spin dynamics in ferromagnetic metal on a femtosecond timescale. The interaction of light and matter on ultrafast time scales aims to develop new concepts for the generation of THz radiation.
