Abstract
The microwave absorption and structural studies of BiSrCaCuO (2212) whiskers have been performed. The low-angle boundaries in the (a, b) and (a, c) planes have been observed. The periodic microwave absorption signal indicated the flux quantization in a system of weak links and superconducting loops formed on the boundaries. Regular character of this signal suggests possible applications in SQUID magnetometry. Lower Josephson critical fieldH clJ=1.6 Oe and the critical temperatureT c=89 K have been determined. The Josephson penetration depth was estimated from the Ginzgurg-Landau, and Clem models.
