EPITAXIAL YBa 2 Cu 307 ON BIAXIALLY TEXTURED ( 001 ) NI : AN APPROACH TO HIGH CRITICAL CURRENT DENSITY SUPERCONDUCTING TAPES
In-plane aligned, c-axis oriented YBazCu307 (YBCO) films with superconducting critical current densities, Jc, as high as 700,000 amperes per square centimeter at 77 kelvin have been grown on thermo-mechanically, rolled-textured (00 1) Ni tapes using pulsed-laser deposition. Epitaxial growth of oxide buffer layers directly on biaxially textured Ni, formed by recrystallization of cold-rolled pure...
متن کاملInterdiffusion studies on high - T , superconducting YBa , Cu , O , _ , thin films on Si ( 111 ) with a NiSi , / ZrO , buffer layer
Interdiffusion studies on high-T, superconducting YBasCu,O,_s thin films with thicknes~s in the range of 2000-3000 A, on a Si(ll1) substrate with a buffer layer have been performed. The buffer layer consists of a 400 A thick epitaxial Nisi, layer, covered with 1200 A of polycrystalline 210,. YBa,Cu,O,_s films were prepared using laser ablation. The YBa,Cu,O,_, films on the Si/NiSi,/ZrOs substra...
متن کاملAdvantageous grain boundaries in iron pnictide superconductors
High critical temperature superconductors have zero power consumption and could be used to produce ideal electric power lines. The principal obstacle in fabricating superconducting wires and tapes is grain boundaries-the misalignment of crystalline orientations at grain boundaries, which is unavoidable for polycrystals, largely deteriorates critical current density. Here we report that high cri...
متن کاملPhotoinduced superconductivity and structural changes in high temperature superconducting films
The illumination of Pr,,Gd, -,Ba,Cu,O, semiconducting and superconducting thin hlms increases their critical temperatures and decreases their normal state resistivities if and only if the films are oxygen deficient. Moreover, these changes are enhanced near the Pr-induced metal-insulator transition. Light also causes a contraction of the c-axis in YBa,C!u,O, which is correlated with the observe...
متن کاملCritical Current Density of YBa 2 Cu 3 O 7 − δ Low - Angle Grain Boundaries in Self - Field
A study has been perfomed on the superconducting critical current density Jc flowing across low angle grain boundaries in epitaxial thin films of YBa2Cu3O7−δ (YBCO). The materials studied were dual grain boundary rings deposited on SrTiO3 and containing 2 , 3, 5 and 7 tilt boundaries. The current density in self-field was determined by magnetometric methods at temperatures from 5 K to Tc. We co...
