Abstract
An NMR rotor comprises a receptacle for inserting a sample container into a homogeneous region of an NMR magnetic field with flux density B, the field vector of which in the homogeneous region extends in the vertical direction along a z-axis. The rotor passes through regions with inhomogeneous magnetic field components and a flux density gradient dB/dz when the sample container is introduced. The rotor includes at least two different materials, one with diamagnetic properties and another with non-diamagnetic properties. The different materials are arranged to be geometrically distributed in the rotor so that the magnetic force on the rotor under the effect of a product t of magnetic flux density B and flux density gradient dB/dz, the magnitude of which exceeds 1400 T/m, either acts in the same direction as the weight force of the rotor or is smaller in magnitude than the weight force of the rotor.
