    Atomic force microscope analysis indicated the surface of such films was smooth, dense and crack-free. mu m-thick YBCO films were prepared directly on this 2-layer template with a critical. Abstract: We developed a non-destructive and contactless system for measuring the critical current (I c) in YBa 2 Cu 3 O 7-δ (YBCO)-coated conductors by using a permanent magnet (Sm 2 Co 17).This I c measurement method is based on the repulsive force (F r) between the magnet and the shielding current in high-temperature superconductor-coated conductors.

    The YBCO coated conductor (CC) is one of the most promising superconductors for various superconducting applications. Although it has many advantages, joints of the YBCO CC are inevitable because there are technical difficulties in lengthening the YBCO CC. In the joining process, it is important to reduce the joint resistance between the YBCO CCs in order to operate in a persistent current mode.

    In addition, other ferromagnetic nanoinclusions such as of YFe 3 O 4 [] and CoFe 2 O 4 [] have also been successfully used to enhance the vortex pinning properties of YBCO thin films. The. Applications of YBa2Cu3Ox (YBCO) coated conductors require strong vortex pinning to ensure a non-dissipative state over a large range of temperatures and magnetic field values.

Substrates, known as coated conductors (CC), is a topic of enormous technological importance. Traditionally, the highest YBCO Jcs have been obtained for thin films on single crystal substrates (SCS), with values that exceed by orders of magnitude those measured in YBCO single crystals.

Here, we report the delamination strength, measured with a new experimentaltechnique,of YBCO coated conductors that have a laminar YBCO grain structure. The critical current (I c) is measured as a function of transverse tensile stress to verify whether the critical.

Experimental technique. We report on electrical transport measurements at high current densities on thin films of optimally doped YBCO grown on vicinal SrTiO 3 substrates. Thin films were prepared by pulsed laser deposition and grown on single crystal SrTiO 3 substrate, miscut by an angle α towards the (0 0 1) t tracks were patterned by photolithography and Ar-ion milling.

The effect of hybrid (columnar and spherical together) artificial pinning centers (APCs) on the vortex pinning properties of YBa 2 Cu 3 O 7− δ (YBCO) thin films is investigated in detail on the basis of variation of critical current density (J C) with applied magnetic field and also with the orientation of the applied magnetic field at 65 K.

Despite the complexity of the structure, after the optimization of the deposition procedure, the YBCO/BZO showed only a moderate reduction of Tc with respect to the pure YBCO.

Many studies have been conducted on the applications of the HTSCs in electric power and energy transmission systems. The recent achievement of a critical current density of 10 6 A cm −2 in small samples of YBa 2 Cu 3 O 7 (YBCO)-coated conductors has stimulated interest in manufacturing economic long-length YBCO-coated conductors.

The conductors will be exposed to neutron radiation in a fusion magnet, which could potentially improve or degrade their properties. Industrial YBCO coated conductors were characterized by magnetization and direct transport measurements in magnetic fields of up to 15 Tesla and at temperatures between 50 and 85 K.

deposition of 70nm thick CeO2 cap layer onto YSZ, YBCO films were deposited employing a high-rate pulsed laser deposition (HRPLD). At the last processing step, the CC tapes were coated with thin shunt layer of silver or gold, µm thick, and with a 20 to 40 µm thick copper shunt layer.

We report electrical transport measurements of thin YBCO-films with three different oxygen contents in the mixed state, with a magnetic field applied perpendicular to the CuO 2 layers. We have analysed our resistivity data in the framework of two models: the thermally activated flux-flow model and the vortex-glass theory.

The thermally activated flux-flow model yields an interesting result.The existence of non-superconducting zones in YBa2Cu3O7−δ (YBCO) films below the transition temperature to the non-resistive state can limit the performances of YBCO devices, especially of coated conductors for power transportation.
