抄録
The magnetic level of the Meissner state in high-Tc oxide thin films is investigated using scanning superconducting quantum interference device microscopy. We find that the Meissner level observed is not uniquely determined and shifts with the temperature and depends on the doping level of individual oxide films. The result at higher temperature may be interpreted by a grain-coupled model which reflects the granular nature of high-Tc oxides and is useful for evaluation of high-Tc film quality.
