Enhancement of Flux Pinning in YBa ₂Cu ₃O _7-δ Thin Films Embedded with Epitaxially Grown Y ₂O ₃ Nanostructures Using a Multi-Layering Process

Vortex pinning in the frozen vortex lattice in YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} films

Xenikos, D.G. ; Cunningham, A.E. ; Lemberger, T.R. ; ... - Physical Review, B: Condensed Matter

The inductance of vortices {ital L}{sub {ital V}}({ital T},{ital B}) in YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} films is studied for temperature 8{lt}{ital T}{lt}85 K, and magnetic field 0{lt}{ital B}{lt}6 T with the goal of identifying the morphology of the vortex pinning sites and the type of the glass phase below the vortex lattice melting transition {ital B}{sub {ital g}}({ital T}). The key feature that distinguishes point, linear, and planar pinning sites is how rapidly {ital L}{sub {ital V}} increases when thresholds in {ital T} and {ital B} are crossed. We find that, below a threshold field {ital B}{sub {ital p}}({italmore »« less

Cross-flux effect as a vortex pinning process in YBa[sub 2]Cu[sub 3]O[sub 7] and Y[sub 0. 8]Pr[sub 0. 2]Ba[sub 2]Cu[sub 3]O[sub 7] crystals

Park, S.J. ; Kouvel, J.S. ; Radousky, H.B. ; ... - Physical Review, B: Condensed Matter; (United States)

In both crystals at 4.2 K, a trapped flux along the [ital c] axis is seen to inhibit the initial production of vortex flux by external fields ([ital H][sub [ital e]]) in the [ital a]-[ital b] plane and to increase the retention of this vortex flux during subsequent cycling of [ital H][sub [ital e]]. Thus, the cross flux along [ital c] acts consistently as a pinning agent for the vortices aligned along [ital a]-[ital b]. The cross-flux effects in both these crystals are as pronounced as those observed in grain-oriented YBa[sub 2]Cu[sub 3]O[sub 7] [S. J. Park and J. S.more »« less

Vortex pinning and twin boundaries in YBa sub 2 Cu sub 3 O sub 7 minus. delta. thin films

Lairson, B.M. ; Streiffer, S.K. ; Bravman, J.C. - Physical Review, B: Condensed Matter; (USA)

The interaction between magnetic flux vortices and twin boundaries is investigated in YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} thin films. Films grown to various thicknesses, and cooled along different paths in the YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} phase diagram, are shown to have various twin boundary microstructures and densities. It is demonstrated that changes in processing result in differences in the vortex-pinning behavior of the films, but that these differences are not due to changes in the microstructure of the twin boundaries. Further, observed differences in the twin spacing do not result in changes in the volume pinning force. This is found tomore »« less

Phase-Separated, Epitaxial, Nanostructured LaMnO ₃+MgO Composite Cap Layer Films for Propagation of Pinning Defects in YBa ₂Cu ₃O _7-x Coated Conductors

Wee, Sung Hun ; Shin, Junsoo ; Cantoni, Claudia ; ... - Applied Physics Express

Nanostructural modulation in the cap layer used in coated conductors can be a potential source for nucleating microstructural defects into the superconducting layer for improving the flux-pinning. We report on the successful fabrication of phase separated, epitaxial, nanostructured films comprised of LaMnO{sub 3} (LMO) and MgO via pulsed laser deposition (PLD) on biaxially-textured MgO metallic templates with a LMO buffer layer. Scanning Auger compositional mapping and transmission electron microscopy cross sectional images confirm the nanoscale, spatial modulation corresponding to the nanostructured phase separation in the film. YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} films (0.8 {micro}m thick) grown using PLD on such phasemore »« less
