Abstract
An NMR spectroscopy system for studying a region of a sample to be analysed, includes a magnetoresistive transducer made up of superposed planar layers, which receives a response signal of the sample; a system for making an AC current flow, at a supply frequency f, through the transducer; a system for generating a magnetic field Hthat is constant and uniform throughout a zone of interest in which the sample and transducer are placed; and an exciting coil to generate a magnetic field Hthat is uniform throughout the zone of interest and that varies at a resonant frequency f; the field His substantially perpendicular to the layers of the transducer. The system further includes a regulating system to ensure that the field Hand the planar layers remain orthogonal, and a system for detecting a signal of frequency f−f, f−for f+f.
