摘要：

Gd1+xBa2-xCu3O7 (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 similar to 100 A/cm at 0.5 micron-thick films. In our measurement of Raman scattering spectroscopy from 180 similar to 1,200 cm(-1), one strong B-1g mode and two strong A(1g) 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 BaCuO2, which is a signature liquid phase-based material that occurs in other rare-earth based cuprates.
