Abstract

The dense Ti-doped MgB₂/Cu tapes with Ta as a buffer layer were prepared using in situ powder-in-tube method. The tapes were sintered at 900-950°C for 2-3 hours in argon, and superconducting properties, structure and microstructure results were presented. It was found that Ti doping enhanced the flux pinning, and high critical density values were obtained in Mg_0.9Ti_0.1B₂ tape. Microstructure analysis showed that the tapes with Ti doping were dense and consisted of fine MgB₂ particles, with a thin layer of TiB₂ and MgO nanoparticles.
