Abstract

We have investigated critical current Ic properties of 600 A/cm-class GdBa2Cu3O7-δ (GdBCO) coated conductor(CC) deposited on IBAD template. 2.5 μm thick GdBCO layer has been obtained by pulse laser deposition without degradation of critical current density by an improved heating condition in reel-to-reel deposition process. This enables stable production of long length CC with Ic (77 K, self-field) of 600 A/cm-w. In-filed Ic has also shown high value e.g.,Ic@77 K,3T = 33 A/ cm-w Ic@20 K, 27 T = 107 A/ cm-w These experimental results obtained in a wide range of bias conditions of temperature , magnetic field and field angle are useful as a fundamental data for design of superconducting devices such as coil winding and magnet. Furthermore, we have also shown that our proposed analytical expression of electric field vs. current density (E-J) characteristics agrees well with the experimental results. This analytical expression allows us to predict I c-B-T property as well as characteristics at arbitrary conditions of and B and T.
