摘要

NMR magnetometer probe with a tuneable cavity in its center and a double central cylindrical member. The tuning element of the cavity is a capacitor placed in the center of the resonant cavity between two half sections of the central conductor. This capacitor is regulatable and a magnetic being accessible through an opening. Application to the measurement of magnetic fields, particularly the geomagnetic field.
