Abstract

Building efficient and ultrabroadband terahertz (THz) emitters remains a challenge in the field of THz photonics. Recently, spintronic THz sources emerged as a promising platform to fulfill the technological needs in terms of large THz bandwidth, high THz amplitude and versatility. In this talk, I will highlight the recent advances in studying laser-induced ultrafast spin and charge currents in magnetic heterostructures. Our results not only provide a basic understanding of ultrafast spintronic effects but might even allow one to further boost the perfomance of spintronic THz sources in the future.
