(Received January 14, 2005; accepted February 23, 2005; published June 10, 2005)

NMR measurements up to 30 T were performed with the hybrid magnet installed in the National Institute for Materials Science (NIMS). The field profile and stability of superconducting, resistive and their hybrid magnets were measured using ⁶³Cu NMR of a Cu metal. The field homogeneity of the hybrid magnet at 30 T is 186±4 ppm in the region ±5 mm from the field center along the z-axis. The magnetic field fluctuates with a total amplitude of about 30 G at 30 T (100 ppm). The present status of the hybrid magnet for high-resolution solid-state NMR measurements is discussed.
