Rapid-scan electron paramagnetic resonance using an EPR-on-a-Chip sensor [PDF]

Magnetic Resonance, 2021
Abstract. Electron paramagnetic resonance (EPR) spectroscopy is the method of choice to investigate and quantify paramagnetic species in many scientific fields, including materials science and the life sciences. Common EPR spectrometers use electromagnets and microwave (MW) resonators, limiting their application to dedicated lab environments.
