Titania doping effect on superconducting properties of MgB2 bulk samples (original) (raw)

Journal of Physics: Conference Series, 2009

Abstract

In this work we study the microstructural and superconducting properties of doped and undoped bulk MgB2 samples prepared by solid-state reaction, with 0 and 2.5 %at. nominal TiO2 nanotubes contents, annealed at different temperatures in the 750-900°C range. We discuss the Tc, Jc and Hc2 performance and their correlation with the different synthesis parameters.
