Use of a phase-sensitive detector for measuring losses in superconductors as a function of frequency.

Summary

The method follows a suggestion which notes that, for a symmetric hysteresis loop, one can trace out the loop by measuring the output voltage of a phase-sensitive detector as a function of the phase angle between the applied field and the detector setting. The authors have measured the losses at 77 K in aligned YBCO for frequencies from 10 hertz to 40 kilohertz with amplitudes of applied field up to 100 oersteds. Results are similar to those of the usual method (in-phase component of dB/dt).
