摘要：
An additional broad peak in the imaginary part of AC susceptibility of Bi2Sr2Ca1Cu2Ox tapes is observed. Using the model of separated stacks, it is found that the peak reflects the near grain boundary intergrowths of Bi2Sr2CuOx. Kosterlitz-Thouless transition temperatures of different stacks for Bi2Sr2Ca1Cu2Ox and Bi2Sr2CuOx are determined. The presence of intergrowths is confirmed by the direct TEM measurements.
