A nuclear magnetic resonance (NMR) spectrometer with a magnet arrangement (1) for generating a homogeneous static magnetic field B0 in the direction of a z axis and a radio frequency (RF) resonator (2) 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 BT, transverse to the homogeneous magnetic field B0, which acts on the superconducting components of the RF resonator (2), 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.
