Abstract
We studied the Ti doping effect on the superconducting properties and microstructure of sintered MgB2 bulk polycrystals. Using Ti as a sintering assistant, we have fabricated MgB2 bulk materials consisting of fine 10 nm scale particles and achieved a high Jc of 1MA/cm2 in self-field and 3 x 105 A/cm2 in 1T at 20 K. The large enhancement of Jc is explained by the excellent connection between grains and the high density of pinning centers served by both grain boundaries and MgO nanoparticles.
