Abstract

In this work, we report on significantly enhanced critical current density (J_c) in MgB₂ superconductor that was easily obtained by doping with a hydrocarbon, highly active pyrene (C₁₆H₁₀), and using a sintering temperature as low as ∼ 600 °C. The processing advantages of the C₁₆H₁₀ additive include production of a highly active carbon (C) source, an increased level of disorder, and the introduction of small grain size, resulting in enhancement of J_c.
