Outline of Final Research Achievements |
A magnetic field is predicted to emerge on a particle in a rotating object. This emergent field is called a "Barnett field". We show that nuclear magnetic resonance (NMR) enables a direct measurement of the Barnett field in solids. We rotated both a sample and a NMR coil synchronously at high speed and found an NMR shift whose sign reflects the sign of the nuclear magnetic moments. The result provides direct evidence of the Barnett field. NMR for the Barnett field enables the unknown signs of nuclear magnetic moments in solids to be determined.
