Abstract

Abstract A lightweight, low-cost electron spin resonance (ESR) spectrometer utilizing Nd-Fe-B permanent magnets has been developed. A basic model is only 2 kg in weight and is now commercially available as “Spin-X” for educational purposes. Magnetic field modulation added to this portable spectrometer has improved the sensitivity by nearly two orders of magnitude, using a sample holder with a field modulation coil.
