摘要： An antenna coil is formed by a wire rod obtained by combining and integrating two or more kinds of materials having different magnetisms. The wire rod 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 rod is wound around a bobbin so as to have a solenoid shape. Desirably, the low-magnetic wire rod is placed in an atmosphere whose temperature has been reduced to 10° K or less or superconductive filaments are formed in the outermost layer. Preferably, a part of the superconductive filaments are exposed.

摘要： An NMR system that enables multiplex resonance measurement includes a superconductivity reception coil, a transmission coil, and four electric current loops. The NMR system also includes an additional coil in which directions of currents that flow in an inner loop and an outer loop are opposite to each other. The additional coil and the transmission coil are arranged such that a direction of a high frequency magnetic field that is developed in the center of the additional coil when electricity is fed to the additional coil is substantially identical with a direction of a high frequency magnetic field that is developed in the center of the transmission coil when electricity is fed to the transmission coil. The electric current loop of the transmission coil is arranged substantially in the middle of the inner loop and the outer loop of the additional coil in which directions of electric currents that flow in the inner loop and the outer loop are opposite to each other.
