Barnett effect, magnetization by body rotation, is one of the fundamental phenomena of the angular momentum conversion between electron spin and mechanical rotation. Recently, the effective magnetic field that induces the Barnett effect has been observed directly in terms of the solid state nuclear magnetic resonance (NMR) in which a sample and a detector are synchronously rotated.
In this presentation, we will discuss effects of mechanical rotation on NMR spectra by changing the tilt angle between the spinning axis and an external magnetic field and the coil angle between the spinning axis and the detection coil axis. We will also discuss the relation between the NMR spectra and Berry phase accumulations for an arbitrary nuclear spin I.
