Abstract

The effects of Ti ₃SiC ₂ doping on lattice parameter (a), microstructure, critical temperature (T _c) and critical current density (J _c) of MgB ₂ superconductors were studied. Carbon substitution for boron could be confirmed by the shrinkage of the lattice parameter a with increasing of Ti ₃SiC ₂ doping level. A reduction of T _c from 37.15 K to 36.55 K with increasing of Ti ₃SiC ₂ doping was observed. The J _c values were determined by M-H hysteresis loops. Results show that in low magnetic field region, the J _c value for the undoped sample is higher than those for the doped samples. However, with the increase of the magnetic field, the J _c for the properly doped samples will be enhanced.
