ABSTRACT
Samples with composition Y1-xGdxBa2Cu3O7 (x=0.001–0.005) are prepared and TC, ΔTC, JC, ρ(300 K) are measured. It is shown that upon substituting yttrium by small amounts of gadolinium, JC can be improved significantly. The anticorrelation of JC with ΔTC and ρ(300 K) is established. The possible role of gadolinium in enhancing JC is discussed. General guidelines for getting high JC values are gathered.

    YBaCu3O7-δ thin films were grown on vicinally polished MgO [001] substrates. The orientation of the films is strongly influenced by the substrate surface normal, with only very weak alignment to the substrate [001] crystallographic direction. Vicinal angles of 1°, 2.5°, and 5° toward...

    We propose an inductive method to measure critical current density J[sub c] in bulk superconductors. In this method, an ac magnetic field is generated by a drive current I[sub 0] flowing in a small coil mounted just above the flat surface of superconductors, and the third-harmonic voltage V[sub...

    Critical currents of the new high-temperature superconductor Y1Ba2Cu3O7 have been measured in applied fields of up to 7 T and for temperatures down to 70 K. We find that the critical current is drastically reduced by the application of magnetic fields much smaller than the upper critical field...

    The critical current density (Jc) at 77 K and in 0 T of more than 3000 A/cm2 has been obtained in the silver sheathed Bi-Pb-Sr-Ca-Cu-O tape fabricated by the combination process of sintering and intermediate cold working. The decrease of the Jc with increasing magnetic field is much smaller in...

    Critical current densities (Jc) in YBa2Cu3O7-x films made at deposition rates from 0.1 to 14.5 nm/s (∼50 μm/h) were measured using a direct transport method. As the deposition rate was increased by two orders of magnitude, the films exhibited no marked degradation in current carrying...
