The superconducting critical temperature was reduced due to the presence of CM0 layers. The longitudinal resistivities under a magnetic field parallel to the c-axis shows a thermally activated behavior and pinning energy decreases with an increasing magnetic fields or currents applied. The pinning abilities are also affected by the thickness of YBCO or CM0 layers. The negative Hall coefficient in the mixed-state depends on the flux pinning and decreases as the pinning force decreases. The results are consistent with the Wang and Ting s model [lo].application/pdf185892 bytesapplication/pdfzh-TWjournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/20060927115952242995/1/394.pdf
