PROBLEM TO BE SOLVED: To provide a solid-state NMR probe that can be easily constituted by a nonmagnetic material, is simple, and saves space. SOLUTION: This solid-state NMR probe is equipped with a sample spinner for rotating a sample tube about an axis tilted at 54.7°with respect to a magnetostatic field axis of a superconducting magnet and is inserted into a longitudinal hole of the superconducting magnet. The solid-state NMR probe has a mode for tilting the sample spinner by 54.7°, from the direction of the static magnetic field of the superconducting magnet and rotating the sample tube in the sample spinner at a high speed, and a mode of making the rotation axis of the sample spinner coincide with the magnetostatic field direction of the superconducting magnet, and taking the sample tube into or out of the longitudinal hole of the superconducting magnet in the vertical direction. The switching between both modes is performed by using expansion and contraction of a shape memory wire as a driving source. COPYRIGHT: (C)2008,JPO&INPIT
