Abstract
A nuclear magnetic resonance (NMR) spectrometer with a magnet arrangement ( ) for generating a homogeneous static magnetic field B in the direction of a z axis and a radio frequency (RF) resonator ( ) for receiving NMR signals from a measuring volume which has one or more superconducting components, is characterized in that a stabilization device is provided which keeps the magnetic field components B , transverse to the homogeneous magnetic field B , which acts on the superconducting components of the RF resonator ( ), constant. The stabilization device can act actively or passively. It is thereby possible to completely suppress generation of disturbing transverse magnetization for RF resonator coils with superconducting components. Moreover, a demagnetised coil always remains demagnetised during the entire subsequent operation.
