A process for the characterization of materials for use in the resonance - magneto flank geometry, a spectrometer for this characterization and method for calibration of this spectrometer.

摘要

P method of characterization of materials for their use in magnetometry to resonance spectrometer for this characterization and method of calibration of the spectrometer. / p & & p & it determines the value of the greatest slope of the curve of a dispersion of the material to be tested, around a reference frequency fr. for this purpose, use is made of a spectrometer at the head of the bloch orientable and operating in a range of frequencies ranging from 1 to 2 mhz. The spectrometer, in order to make it possible to optimize the slope, must be calibrated by subjecting the coil 14 of the detection of a magnetic field known calibration and by measuring the voltage across the terminals of this coil 14. / p & & p & application to the classification of materials for their use in electron paramagnetic resonance. / p
