| 中文摘要 | By using thermal and Lorentz force, the vortex motion is successfully manipulated in the mixed state of underdoped La2-xSrxCuO4 single crystals and optimally doped YBa2Cu3O7-delta thin films. A conclusion is drawn that the strong Nernst signal above T-c is induced by vortex motion. In the normal state, in order to reduce the dissipative contribution from the quasiparticle scattering and enhance the signal due to the possible vortex motion, a new measurement configuration is proposed. It is found that the in-plane Nernst signal (H parallel to c) can be measurable up to a high temperature in the pseudogap region, while the Abrikosov flux flow dissipation can only be measured up to T-c. This may point to different vortices below and above T-c if we attribute the strong Nernst signal in the pseudogap region to the vortex motion. Below T-c the dissipation is induced by the motion of the Abrikosov vortices. Above T-c the dissipation may be caused by the motion of the spontaneously generated unbinded vortex-antivortex pairs. |
