Abstract
An additional broad peak in AC losses of Bi2Sr2Ca1Cu2Ox tapes is obser ved. Using a new method based on the model of separated finite-size st acks of superconducting layers it is found that this peak reflects the presence of Bi2Sr2CuOx intergrowth in the sample. Kosterlitz-Thouless transition temperatures of pure Bi2Sr2Ca1Cu2Ox and intergrowths of di fferent thickness are defined. Our results are confirmed by the direct TEM measurements.
