The spintronic Terahertz (THz) emission of thin magnetic/heavy metal bilayers with fs laser excitation is an excellent alternative to the well-known bulk nonlinear crystals. Many works have been published about different material combinations of spintronic emitters, but the properties of the bilayer interface and its influence on the THz emission is not well understood. We study Fe/Pt interfaces, which were modified by implantation with foreign atoms to investigate the influence of the interface on the THz emission. THz-Time Domain Spectroscopy and SQUID-VSM Magnetometry, as well as high-resolution Scanning Transmission Electron Microscopy (STEM) with Energy Dispersive X-Ray Spectroscopy (EDS) were performed to understand the effects of the modifications.
