摘要：
The Bitter decoration technique is one of the most powerful techniques to study the vortex structure of superconductor. We report the observation of vortex structure in a high TcYBa2Cu3O7−y(YBCO) thin film by Bitter decoration method. The image of vortex structure was monitored by SEM, AFM and high resolution optical microscope. For magnetic field about 4-6mT,a vortex structure is seen. The vortex image varied with changing magnetic field. As compared with the vortex image of a Bi2Sr2CaCu2O8+ysingle crystal, the observed image appeared to be more randomly distributed.
