Abstract

The graphene doped MgB₂ bulks were synthesized by graphene doping directly, graphene-acetone solution doping, and graphene coating B doping, and the microstructure, critical current density, flux pinning properties were studied. The critical current density of MgB₂ by graphene doping directly gets significant enhancement at low field. However, the superconducting properties for samples synthesized by solution process and coating method do not improve obviously due to the oxidation decreases the activity of B powders.
