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.
