Abstract

Disclosed is an organic material with a very narrow electronic spin resonance (ESR) line. This material is formed by a 1, 2, 7, 8-tetrahydrocyclopentataperylene salt which may have, advantageously, undergone a heat treatment. The material can be applied to the fabrication of probes for gaussmeters and magnetometers.
