摘要： A probe for nuclear magnetic resonance (NMR) measurement provided with a multiple resonant circuit for detecting signals of two or more nuclides with high detection efficiency for nuclide at low resonant frequency comprises a multiple resonance radio frequency (RF) coil circuit that, with multiple lead lines connected to the RF coil, causes a part of the RF coil, separated by the connection points of the lead lines, to function as the inductor of a trap circuit that cuts off a signal at the frequency F1 for a signal at the resonant frequency F1 of a first nuclide and, at the same time, to function as an RF coil that detects a signal at the frequency F2 for a signal at the resonant frequency F2 of a second nuclide, thus increasing the signal detection efficiency for the nuclide at the frequency F2.

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： There is provided a nuclear magnetic resonance probe in which the loss caused by a high frequency cable between a probe coil and a preamplifier is reduced and the sensitivity of an NMR signal is improved. A changeover switch for NMR probe is divided into a switch part including switch elements and a filter part for filtering a switch control signal and an RF transmission signal. The switch part is disposed in a probe body inserted in a magnet of the probe. The filter part is disposed near a measurement apparatus located outside the probe. As for the switch part, a section structure of thickness and width is reduced in conformity with a narrow and slender shape of the probe body. The length of a high frequency cable between the probe coil and the preamplifier is shortened remarkably, and consequently the loss can be reduced.
