Abstract

Extensive work on radical ESR (electron spin resonance) materials has led to the discovery of a number of products exhibiting intense and narrow ESR lines, suitable for magnetometry. These materials can be classified using a convenient figure of merit. Two of them were used in two specific architectures for a scalar magnetometer-(FA₎2P((fluoranthenyl)₂PF₆)-₆ with a resolution of 1 nT-Hz^-1/2 (white noise) and a vectorial magnetometer (AcTCNQ₂) with a resolution of 0.2 nT-Hz^-1/2 (white noise). These magnetometers can be used in high gradients (usual indoor environments) and have bandwidths which can be extended from DC to several kHz
