New Cavity Design for Broad-Band Quasi-Optical HF-EPR Spectroscopy

  • Petr Neugebauer
  • Anne-Laure BarraEmail author


The design and performance of two new devices adapted for high-frequency electron paramagnetic resonance (HF-EPR) in a broad frequency range are described. Both systems, a Fabry–Pérot resonator and a rotating sample holder, rely on similar construction schemes and on the use of submicrometer piezoelectric positioners. A study of a single crystal of graphite allows illustrating the operation of these two new systems associated with our quasi-optical HF-EPR spectrometer.
