Rutter, NA and Durrell, JH and Mennema, SH and Blamire, MG and MacManus-Driscoll, JL (2005) Transport properties of Ca-doped YBCO coated conductors. In: UNSPECIFIED pp. 2570-2573..Full text not available from this repository.
The authors have doped RABiTS coated conductor tapes with Ca in an attempt to enhance the transport properties. By diffusing Ca into the YBCO film from a CaZrO3 overlayer, the authors have been able to preferentially dope the grain boundaries of the superconductor. Hence it has been possible to obtain doped tapes which do not have a significantly degraded T-c. The authors have measured the critical currents of doped and undoped samples over a wide range of temperature, magnetic field, and magnetic field angle in order to study the effect of Ca on the grain boundaries. The authors find that doping using short anneal times produces enhanced critical currents in large magnetic fields.
