Abstract :
MgB2 bulk samples doped with sucrose were fabricated with the formula MgB2-xCx(x = 0, 0.08, 0.12, 0.2, 0.3, 0.5). Appropriate amounts of sucrose corresponding to the desired carbon content were added. The doping effect of sucrose was observed. It was found that samples doped with x = 0.2 sucrose have optimized current density at high magnetic field. The optimized sintering temperature for high current density was found to be 850degC. Hc2 and Hirr were both found to be improved due to the sucrose doping.
