摘要: Abstract Superconductivity of BSCCO single crystals in which some CuO 2 trilayers are inserted the Bi Sr CaCu O 8 matrix is studied. The curvatures I-V curves for change from negative to positive with increasing field, and scaling behaviour a vortex-glass state observed. I c found obey relation = c0 (1 − T / ) α 1.2. Our results reveal that transition exists system constructed trilayers.
