Effect of Ti-Doped on Y134 Superconductor

Abstract

We investigated some properties of Y134 superconductor doped Ti superconductor. The series of samples of Y134 doped Titanium (YBa3Cu4TixO9-δ) which x=0, 0.05, 0.10, 0.15, 0.20, 0.25 were prepared by solid state reaction method with calcinations and sintering temperature at 980 °C. The porosity was reduced and the melting area were found for all Ti-doped samples. There was a little effect of Ti-doped on Tc onset but the lower of Tc offset were found that agree with the melting found on surface of sample with Ti-doped. The peritectic temperature of Y134 powder, and Y134 + 0.10Ti were on the same range about with more peak area of pure Y134 than Y134 with Ti-doping.
