FeSe tapes have been prepared by using a diffusion method. By adjusting the reaction temperature and the thickness systematically, a transport critical current density as high as 600Acm ² at 4.2K under self-field is achieved. Magneto-optical images indicate considerable distribution of T _c and weak-link features in the FeSe tape. This study gives some insight into how to further improve the quality and performance of FeSe tapes and other superconducting tapes prepared through the diffusion method.
