The authors have been developing HoBa2Cu307-x (HoBCO) thin films using pulsed laser deposition (PLD) method. HoBCO shows high critical current density when deposited on single crystal substrate such as sapphire. Based on PLD technique, HoBCO coated conductor has been developed on flexible metal substrate. For the development of HoBCO coated conductor, the authors had originally developed a basic technique of the formation of buffer and superconducting layer. After the basic technique was developed, the authors have started the development oflong-length coated conductors. In the course of this development, the authors had developed the techniques for forming crystal orientated buffer layer and superconducting multi-layer. As the result of the development of long-length conductors, high critical current was achieved by the multi-layer formation of superconducting layer using industrial large-scale excimer laser. Furthermore, with an aim to apply the coated conductor to superconducting magnet, critical current was measured at low temperature and high magnetic field. Excellent high critical current was observed, which satisfies the requirements for the coil of high field magnet such as high resolution NMR magnet.
