Electrically detected magnetic resonance (EDMR) is an effective spectroscopic method used for characterizing semiconductive solid-state materials. High spin sensitivity and the capability to explore spin-dependent transport mechanisms, which are crucial for the development of semiconductor devices, define it from other methods based on magnetic resonance. High frequency and high magnetic field EDMR implementation was motivated by the necessity to obtain access to more precise, high-resolution data to enhance the method’s research potential. We present an EDMR system based on a unique THz FraScan spectrometer, which performs frequency sweeps ranging from 80 GHz to 1.1 THz, and the magnetic field sweeps up to 16 T. The study addresses the instrumentation, detection scheme, and 85–328.84-GHz EDMR results on highly nitrogen-doped 15R SiC monocrystals.
