Abstract
High-T c superconductors are known to have a layered structure: the high conductivity Cu-O planes are separated by low conductivity layers in c direction. Moreover, there are some one-dimensional (1D) crystal structure entities: Cu-0 chains in YBCO compounds and superstructure in BSCCO and TBCCO materials. Because of this structure one might expect 1D behavior of fluctuations besides the 3D [1] and 2D [2–4]. Then, crossovers of the dimensionality due to temperature dependence of coherence length in a high-T c superconductor can be observed.
