中文摘要Measurements of the magnetic relaxation rates S(T) and transport characteristics have been performed on Y1Ba2Cu3O7-delta (YBCO) films with thickness between 2.4 and 200nm. Strong quantum fluctuations of the vortex movements which occur at temperatures as high as 8.5 similar to 15 K are detected in all ultra-thin films (2.4 similar to 40nm), while the thick sample (200nm) does not show any quantum fluctuations at the experimental temperatures down to 4.2K. The experimental results are discussed with the theory based on dissipative tunneling of collectively pinned vortex. It is suggested that the strong quantum fluctuations in the ultra-thin films are due to the higher zero temperature normal state resistivity and/or the higher active energy of them compared to those of the thick sample.
