ABSTRACT:
A method and apparatus for detecting magnetic resonance of a sample. The aratus utilizes an exceptionally stable tunnel diode rf oscillator incorporating a LC reentrant cavity resonator. The method entails measuring a magnetic resonance of the sample through the frequency of the oscillator. The resulting dispersion curve can be utilized to obtain the static magnetic susceptibility of the sample. From the value of the static magnetic susceptibility additional parameters may be determined such as material density, temperature or particle spin. The method and apparatus has applications in NMR, NQR and ESR measurements.
