Abstract:

Reduced graphene oxide (rGO) and highly reduced chemically converted graphene (rCCG) samples were prepared under different processing conditions and were doped into MgB 2 by a diffusion process at 800 °C for 10 hours. It was demonstrated that a small addition rCCG can significantly improve the superconducting properties of MgB 2. Doping of MgB 2 with 1 mol% of rCCG resulted in a J c of 5.45 × 10 5 A cm -2 at 20 K in self-fields, which is nearly 32% improvement over that of the undoped sample. This is a significant improvement as most carbon sources adversely affect the J c performance at the zero field. © 2012 The Royal Society of Chemistry.
