Terahertz Electron Paramagnetic Resonance Spectroscopy Using an Ultrathin Membrane Device

Abstract

A novel terahertz (THz) electron paramagnetic resonance (EPR) spectroscopy technique is presented. The use of an ultrathin membrane device allows sensitive EPR detection of small volume samples in the frequency region up to 0.65 THz. We show THz EPR spectroscopy results on microliter solution of myoglobin and tiny single crystals of magnetically ordered sample.
