摘要：

The rotational motion due to diamagnetic anisotropy was first reported for large single crystals of quartz and corundum, in the magnetic field where the restoring force of the suspending string became negligible. The suspended crystal rotated gradually with the increasing field, and the diamagnetic principal axis was oriented in the direction parallel to the field. Harmonic oscillations were observed for the crystals in high magnetic field, and the period of oscillation was proportional to the reciprocal of the field. The precise value of diamagnetic anisotropy was obtained from the period of oscillation, and was estimated to be 5.45 x 10(-9) emu/cm3 for quartz and 4.19 x 10(-9) emu/cm3 for corundum.
