Abstract
Using a high-Tc radio-frequency superconducting quantum interference device (rf SQUID), wesuccessfully detected nuclear quadrupole resonance (NQR) at about 887 kHz for14N inp-nitrotoluene (PNT). A normal metal transformer made of copper wire was used to improve the sensitivity ofthe high-Tc rf SQUID and pulse-controlled rf switches and cross diodes were inserted in the transformer to reducethe influence of the strong excitation field. The preliminary results for NQR detection using thehigh-Tc SQUID had a similar signal-to-noise ratio to that of using a low noise preamplifier.
