Rotating sample holder without mechanical linkages.
A sample rotator which operates in applied magnetic fields is described. The design eliminates mechanical linkages by magnetically orienting a gimbal ring. Three mutually orthogonal coils mounted on the gimbal provide a magnetic moment which is aligned along the field direction. The rotator is useful from room temperature down to the liquid helium range. Rotations about any desired axis are possible.
