This paper reports the progress of development for coated conductors on metal tapes by the liquid phase epitaxy (LPE) process. It was found that the reaction between the liquid and metal tape can be prevented by the combination of MgO buffer layer and MgO-saturated liquid.

We tried to apply NiO materials as a buffer layer for LPE (Liquid Phase Epitaxy) coated conductors with Ni substrate. We confirmed that NiO could suppress the reaction between NiO/Ni substrate and solution saturated with NiO. On the other hand, NiO addition to the solution decreased the peritectic temperature of the Y123 and increased the crystallization temperature of the Ba-Cu-Ni-O compound. Thi... View full abstract»

For several years, the technical applications of bulk HTS YBCO superconductors are of growing interest. However, for applications which require a complex geometry of the monoliths, the Multi-Seeding Melt Growth (MSMG) and the mechanical joining of two single-domain tiles becomes necessary. However, these two techniques lead to the formation of a low-angle grain boundary (GB). The influence of the ... View full abstract»

We present a study of the remanent magnetization of multifilamentary Ag/Bi-2223 tapes for the magnetic field applied at different angles to the tape surface. Remanent magnetization allows to separate the intergrain and the intragrain contributions. The intergrain magnetization reflects the flow of macroscopic transport currents. We describe the microstructure of the tapes as an agglomeration of pl... View full abstract»

The microstructures of melt-processed Nd-BCO/Ag samples were investigated. A rather homogeneous distribution of Nd422 particles was found, which can be attributed to the fast growing speed of NdBCO and the large size of Nd422 particles. The dispersion of Ag depended on the content of Ag2O, and the phase relation of the Nd-BCO/Ag system is discussed. We also studied the pulsed field magn... View full abstract»

A vital requirement for commercial application of Bi-2223 tapes is that the high critical current densities currently obtainable in short or intermediate lengths can be maintained when piece-lengths are scaled up by more than an order of magnitude. In this paper the effects of statistical variations in local I-V characteristics on the critical current of long superconducting tapes are investigated... View full abstract»
