A THz View on Magnetization Dynamics: Opportunities from the THz userfacility TELBE

In this contribution, we discuss the opportunities arising from the spectrally dense, narrow band, tunable, high repetition rate THz source; TELBE; which recently started user operation. The user facility includes an end station for transient Faraday/MOKE and THz emission spectroscopy and is also equipped with a superconducting split-coil cryo-magnet. Thereby the dynamics of selectively driven resonances in the frequency range between 0.1 and 1.2 THz can be followed with a femtosecond sub THz-cycle time resolution at temperatures between 3 and 300 K and in magnetic fields up to 10T.
