中文摘要 | We report a significant enhancement in upper critical field H(c2) and irreversibility field H(irr) in carbon-doped MgB(2) films fabricated by hot-filament-assisted hybrid physical-chemical vapor deposition (HFA-HPCVD) using methane as the doping source. For the parallel field, a very large temperature derivative -dH(c2)(parallel to ab)/dT value of 3 T K(-1) near T(c) was achieved in a heavily doped film with T(c) near 28 K. Carbon doping also enhanced flux pinning, resulting in a much higher critical current density in a magnetic field J(c)(H) than in undoped samples. The result suggests a more effective doping of carbon into the MgB(2) structure and a better connectivity between the carbon-doped MgB(2) grains than in previous reports. A clear correlation between the decrease in grain size and the enhancement of H(c2) was observed. |
