SUPERCONDUCTING WIRE, METHOD OF MANUFACTURING THE SAME, ANTENNA COIL FOR NMR PROBE AND NMR SYSTEM USING THE SAME

摘要

A superconducting wire, a method of manufacturing the superconducting wire, an antenna coil and a NMR system are disclosed. At least a superconducting material, a paramagnetic material and a diamagnetic material are closely attached and integrated with each other to form a longitudinally continuous wire. The paramagnetic material and the diamagnetic material are arranged in such a manner that the magnetic properties of the paramagnetic material and the diamagnetic material substantially offset each other in the longitudinal and diametrical directions. A superconducting layer is exposed to a part or the whole of the outer periphery of the wire. A low-resistance material layer is formed inside the superconducting layer.
