In order to improve the properties of the as-grown fibers, thermal annealing cycles were performed in both cases at 830 'C for 20 h in air. The samples were quenched in air after each thermal annealing cycle. Characterization of lhe magnetic properties has been performed by mcasuring the in-phase x
Briefly after the single Cu-0-layer-containing compound Bi,Sr,CuO,+, with variable Sr and Cu contents (the so called Raveau-phase or 2201 phase) was found to be superconducting with a critical temperature -10 K,I1] the two and three Cu-0 layer structures were s~nthesized.1~ - This homologous series
