Short segments of YBa2Cu3O7-y (YBCO) coated conductors were fabricated on rolling-assisted biaxially textured substrates (RABiTS) with a layer sequence of CeO2/YSZ/Ni using an ex situ BaF2 precursor process. Pulsed laser deposition (PLD) was used to deposit both YSZ and CeO2 layers. The YBCO films were grown using e-beam coevaporated Y–BaF2–Cu precursors followed by postannealing. An overall engineering current density, JE, of 28,000 A/cm2 and critical current, Ic, of 147 A/cm width at 77 K were achieved for a 1.6-μm-thick YBCO film. This result demonstrates the possibility of using both the ex situ BaF2 precursor approach and the RABiTS process for producing long lengths of high-JE coated conductors.

AbstractHigh-temperature superconductors of the second generation—coated conductors—are based on an architecture of YBCO films deposited on a well-textured substrate tape. The deposition technique used in the processing of YBCO films is responsible not only for both the resulting critical currents in the conductors and the cost efficiency of the employed production route, but also for the ultimate viability of the chosen technology. This article describes an advanced deposition method for YBCO films using high-rate pulsed laser deposition (HR-PLD).An elaborate variable azimuth ablation allows target roughening to be considerably reduced in the course of continuous deposition, and as a result, the integral deposition speed and speed stability can be increased to technologically interesting high values.Well-selected process parameters have been demonstrated to yield high currents of up to 480A/cm-width in short tapes and 360A/cm-width in 6-m-long tapes.Together with quasi-equilibrium heating, the HR-PLD method allows the processing of long-length YBCO-coated conductors and offers a cost-efficient route for their production on an industrial scale.

Several new methods of pulsed laser deposition for fabricating large-area thin films of uniform thickness and composition on a rotating substrate and onto a moving ribbon are proposed. The peculiarities of the methods are the laser deposition of a compound upon a substrate through a diaphragm or the mask placed in immediate proximity of the substrate together with a use of more than one target. The proposed method makes it possible to obtain thin films of uniform thickness on substrates with sizes limited only by the deposition chamber size. Some of the methods are experimentally verified by depositing CuO thin films and the deviation of the film thickness from the average value does not exceed ±3%. Given the advantage of laser deposition, the offered methods should find practical use, in particular, in micro-electronics, optical industry, development of superconducting coated conductors, deposition of thin films of functional materials and other modern technologies.
