MAGNETIC FLUX TRANSFORMER AND COAXIAL THREE-DIOMENSIONA GRADIOMETER

摘要

PROBLEM TO BE SOLVED: To improve detection sensitivity of a magnetic field by suppressing generation of an eddy current with respect to a magnetic flux transformer and a coaxial three-dimensional gradiometer. SOLUTION: A cut part which reaches a reverse surface of a nonmagnetic metal base is provided in a superconducting loop of the magnetic flux transformer including the nonmagnetic metal base and the superconducting loop comprising an oxide superconductor formed on the nonmagnetic metal base and having a shape of plane symmetry about a center axis in a minor-axis direction.
