Circular polarization excitation and detection of (14)N NQR signal are reported. A theoretical model is presented in terms of fictitious spin-1/2 operators and is compared to experiments performed on a powder crystalline sample of RDX. It is shown th

A number of materials related problems have hindered the development of a reproducible process for the fabrication of high-quality SQUIDs and magnetometers. In this paper we discuss the use of GdBa/sub 2/Cu/sub 3/O/sub 7/ and YBa/sub 2/Cu/sub 3/O/sub

We report the development of a wide-bandwidth, low-noise front end to facilitate the high frequency operation of both LTS and HTS DC SQUIDs. A transformer of novel design non-resonantly matches the dynamic impedance of the SQUID through a twisted pai
