Abstract

We have investigated current transport properties in two G1dBa2Cu3O7-δ(GdBCO) coated conductors deposited on different quality of IBAD substrate, i.e., in-plane alignments of the substrate are 1.98° and 2.78°, respectively. From the comparison, Jc enhancement has been confirmed in wide temperature and magnetic field region in the sample using highly oriented IBAD substrate, whereas the irreversibility field and shape of pinning force density (Fp) does not change much. Furthermore, higher in-filed Jc than that of BaHfO3 doped GdBCO coated conductor deposited on standard IBAD substrate has also been observed in practical high field region at low temperature. These results indicate that the improvement of in-plane texturing in the substrate is still very effective even in such range of 2 to 3° to improve in-field Jc.
