Title: Extended electronic structure inhomogeneity created by double chain layer defects surrounding columnar tracks in heavy-ion irradiated YBa₂Cu₃O_7–δ

Abstract

In YBa₂Cu₃O_7–δ (YBCO), heavy-ion irradiation creates continuous amorphous tracks that are highly effective for vortex pinning. However, the electronic structure landscape of defects and consequently their vortex pinning roles are unclear. Here, we show double chain layer (DCL) defects which intersect the columnar tracks are additionally produced by high energy Pb ion irradiation in YBCO. Here, the DCL defects are ~29 nm long, about three times the columnar defect diameter. The electronic structures of the DCL and columnar track defects were determined using atomic-resolution scanning transmission electron microscopy (STEM) and high resolution electron energy loss spectroscopy (EELS). Results show a decrease in the oxygen and copper content at the interface between the track and the YBCO matrix, resulting in interfacial strain. For the DCL defects, the STEM/EELS study revealed a localized electron doped CuO₂ plane next to the DCL defect. The DCL defects thus further extend the electronic inhomogeneity into YBCO.

Irradiation-Free, Columnar Defects Comprised of Self-Assembled Nanodots and Nanorods Resulting in Strongly Enhanced Flux-Pinning in YBa₂Cu₃0_7-δ Films

Journal Article Goyal, Amit ; Kang, Sukill ; Leonard, Keith J ; ... - Superconductor Science & Technology

The development of biaxially textured, second-generation, high-temperature superconducting (HTS) wires is expected to enable most large-scale applications of HTS materials, in particular electric-power applications. For many potential applications, high critical currents in applied magnetic fields are required. It is well known that columnar defects generated by irradiating high-temperature superconducting materials with heavy ions significantly enhance the in-field critical current density. Hence, for over a decade scientists world-wide have sought means to produce such columnar defects in HTS materials without the expense and complexity of ionizing radiation. Using a simple and practically scalable technique, we have succeeded in producing long, nearlymore »« less

Vortex dynamics in YBa₂Cu₃O_7-δ with in-plane columnar defects introduced by irradiation

Journal Article Petrean, Andra ; Paulius, Lisa ; Tobos, Valentina ; ... - Physica. C, Superconductivity

We report on the effects of introducing columnar defects by irradiation in clean single crystals of YBa₂Cu₃O_7-δ in a direction parallel to the ab-plane. The defects were introduced by bombarding the samples with Pb-²⁰⁸⁵⁶⁺ ions at an energy of 1.4 GeV. We find that the defects suppress the first order melting transition for magnetic fields aligned parallel or at small angles relative to the defects. The columnar defects inhibit vortex motion of vortices parallel to the defects, while the vortices experience less pinning when they are perpendicular to the defects. Lastly, our results suggest that the pinning anisotropy is increased,more »« less

Pinning effect on critical dynamics in YBa{sub 2}Cu{sub 3}O{sub 7-delta} films inherent random disorder and with columnar defects.

Journal Article Kim, J -T ; Kang, W N ; Lim, H R ; ... - Physica C

The in-plane longitudinal resistivities of YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (YBCO) films before and after Sn ion irradiation of a matching field 1 T have been measured as a function of magnetic field H ({le}6 T) and temperature T. The extracted fluctuation part of the conductivity {sigma}{sub xx}*(T, H) of the unirradiated sample with inherent random disorder exhibits 3D-XY scaling behavior that reveals dynamic critical exponent z=1.86 {+-} 0.1 and {approx}0.669. The inherent random disorder increases the dynamic critical exponent z to 1.86{+-}0.1 from the value of 1.5 that is for detwinned YBCO single crystal.

Conference Holzapfel, B ; Leghissa, M ; Bauer, P ; ... - Journal of Superconductivity; (United States)

Epitaxial YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] thin films (YBCO) and YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]]/PrBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] multilayers (Y/Pr) were irradiated with high-energy heavy ions (770) Mev [sup 108]Pb under various directions [phi] relative to the c-axis. The irradiation resulted in columnar defects tilted by [phi] from the c-axis. The angular dependence of their pinning activity was studied by measuring the anisotropy of the critical current density. The J[sub c](B, T, [theta]) behavior of the irradiated YBCO thin films showed an additional peak, which exceeds the intrinsic pinning peak, exactly at the irradiation direction.
