Abstract

We fabricated YBa2Cu3Oy coated conductors with 0.4 - 4.0 μm in the thickness on IBAD-MgO template deposited on Hastelloy metal substrates which were heated by a self-heating (S-H) technique in pulsed laser deposition method. The self-heating (S-H) technique is a method to heat a metal substrate by the Joule heat. In addition, preset substrate temperature (T s) was gradually changed during the film deposition. It is possible to suppress a-axis grains even in a thick film by the S-H technique. Critical current density (J c) and critical current (I c) reached 2.0 MA/cm2 and 800 A/cm-width in a film with the thickness of 4.0 μm at 77 K and self-field.
