Abstract
Abstract-Gd1+xBa2-xCu 3Or7(GdBCO) coated conductors on Ion-beam assisted deposition (IBAD)-MgO templates were grown by pulsed laser deposition (PLD). Growth conditions for the PLD of high quality of GdBCO turn out to have a rather larger range than for Nd-based cuprate thin films. The structural properties and critical current of GdBCO have been measured. The GdBCO layers show ∼100 A/cm at 0.5 micron-thick films. In our measurement of Raman scattering spectroscopy from 180 ∼ 1,200 cm-1, one strong B1g mode and two strong modes were observed. The high critical-current is ascribed to well-grown highly textured 123-structure without cation disorder and oxygen deficiency. It is notable that the GdBCO films do not have second phases like, Baco2 which is a signature liquid phase-based material that occurs in other rare-earth based cuprates. ©2009 IEEE.
