ABSTRACT:
To provide a probe coil for an NMR apparatus which can transmit and receive high frequency radio waves with improved Q-factor and S/N ratio. As a measure, the probe coil for an NMR apparatus is provided as of a solenoid type formed of magnesium diboride superconductor. As another measure, the probe coil for an NMR apparatus has a plurality of coils using magnesium diboride superconductors connected in series. As further another measure, there is used a magnesium diboride superconductor mixed with metal. As still further another measure, the probe coil for an NMR apparatus is formed by using a single metal selected from gold, silver, copper, aluminum, iron, platinum, palladium, nickel, stainless steel, chromium, magnesium, tantalum, niobium, titanium, zinc, beryllium, tungsten, or cobalt, or an alloy including a plurality thereof.
