Summary

THE CHANGING MAGNETIZATION OF A SAMPLE IN A SUPERCONDUCTING FLUX TRANSFORMER COUPLED MAGNETOMETER INDUCES A CURRENT IN THE TRANSFORMER WHICH IN TURN CHANGES THE FIELD AT THE SAMPLE. THIS < IMAGE > FIELD AND THE ERROR CAUSED BY IT CAN BE ELIMINATED BY SENSING THE CURRENT IN THE LOOP AND NULLING IT BY FEEDBACK THROUGH A MUTUAL INDUCTANCE. THE AUTHORS HAVE TESTED THE TECHNIQUE ON THE SUPERCONDUCTING TRANSITION OF INDIUM IN AN APPLIED MAGNETIC FIELD AND SHOWN THAT THE OBSERVED WIDTH OF THE TRANSITION IS GREATLY REDUCED BY MAINTAINING ZERO CURRENT IN THE FLUX TRANSFORMER.
