Superconducting properties of coated conductor grown by RABiTS on Ni-Mn tape

A new biaxially textured tape of Ni0.1%Mn was used as a substrate for YBCO coated conductor through the RABiTS approach. Multi-layer CeO2/YSZ/Y2O3 buffer layers and YBCO film were deposited on the substrate by pulsed laser deposition. The YBCO films were deposited at two different deposition rates, corresponding to two different laser repetition rates, 10 and 200 Hz, respectively. Magnetic measurements were carried out on the samples, and the Jc as a function of the temperature and magnetic field was investigated.
