FIG. 1.

Basic concept of fluxoid-based torque realization. and are magnetic fields to generate fluxoid in the ring (flux field) and torque to the ring (torque field), respectively. Josephson junctions and current leads onto the SQUID ring are not shown.

FIG. 2.

Step-by-step procedure to realize the quantum-based torque steps. (a) Magnetic moment vs external flux. , where is effective area of the ring. Dotted slant-lines are magnetic moment of trapped fluxoid for different quantum numbers, the thin solid sawtooth line is the ground state, and the thick solid line is the experimental path. (b) SQUID voltage as a function of external flux. The thin line is modulation of SQUID voltage and the thick line describes the experimental path. The vertical dashed line is ambient field.

FIG. 3.

Schematic describing the effect of the torque field on the magnetic moment of the ring. is the screening current generated to shield out the parallel component due to the angular step and is the resultant magnetic moment correction.
