    A superconducting 100 μm planar coil has been tested for low field cw NMR. The nine-turn 5 nH coil is connected via a planar 1:8 step-up transformer to an external parallel capacitor and resonated at 0.8 MHz to give a Q of 350.
    The tank circuit voltage is measured with a liquid He temperature GaAs MESFET preamplifier.
    Test experiments have been conducted by immersing the Si chip with the planar pick-up coil in liquid and solid 3 He to measure their cw NMR absorptions in the temperature range 0.05 – 0.5 K.
