Abstract
Anomalous oscillations have been observed in surface resistance at 77 K in BSCCO (2212) aged bulk samples in an applied d.c. magnetic field varying fr om 0 to 1000 Oe. The oscillations show similar behaviour when the surface r esistance is measured at different radio frequencies (1.5 and 12 MHz). Thes e oscillations can be explained by considering a mesoscopic network of Jose phson Junctions and loops. The observed hysteresis is attributed to flux pi nning as well as flux trapping in this network. (C) 1999 Elsevier Science L td. All rights reserved.
