| 摘 要： | 为了验证高温超导体中涡旋薄饼运动的存在,我们设计了电流和电位引线分处样品不同表面的实验。实验结果表明,在这种电流电位引线配置下的E～j关系不同于刚性涡旋线运动所预期的E～j关系,由此支持了涡旋薄饼运动的存在。

| Abstract: | In order to demonstrate the existence of the vortex pancake in high temperature superconductor experimentally, a configuration in which the current and voltage electrodes lies separately on the top and bottom surface is used. The E~j relation obtained with this electrodes spatial configuration is different from the expected E~j behavior of the stiff vortex line model. Thus, the current results support the existence of the vortex pancake in high temperature superconductor. |
