Abstract
A precision magnetometer based on pulsed nuclear magnetic resonance (NMR) is described. This magnetometer measures constant magnetic fields with an absolute error not more than 10–6 and a resolution of up to 10–7. The use of modern digital technologies, such as FPGA, made it possible to significantly accelerate and optimize NMR signals. The magnetometer structure is and the signal processing methods are described, measurement errors are analyzed, and experimental data are presented.
