ANTENNA COIL FOR NMR PROBE, AND WIRE ROD AND NMR SYSTEM USED FOR IT

PROBLEM TO BE SOLVED: To provide an antenna coil made of a material having characteristics of both low magnetic susceptibility and a high Q value, and the material. SOLUTION: The antenna coil is made of a wire obtained by combining and integrating two or more kinds of materials having different magnetisms. The wire has a circular or polygonal cross-sectional shape. The two or more kinds of materials having different magnetisms are combined so that the magnetisms of the combined materials are set off. The wire is wound around a bobbin so as to have a solenoid shape. Preferably, the low-magnetic wire is placed in an atmosphere whose temperature has been reduced to 10 K or less or comprises superconductive filaments in its outer peripheral portion. Preferably, a part of the superconductive filaments is exposed. COPYRIGHT: (C)2008,JPO&INPIT
