【 摘 要 】

This is a multiyear experimental research program that focuses on improving relevant material properties of high-critical temperature (T(sub c)) superconductors and developing fabrication methods that can be transferred to industry for production of commercial conductors. The development of teaming relationships through agreements with industrial partners is a key element of the Argonne National Laboratory (ANL) program. A transport critical current density (J(sub c)) of 1.2 x 10(sup 6) A/cm(sup 2) was measured with a sample made with the standard inclined substrate deposition (ISD) architecture. Recent results are described from a study of SrRuO(sub 3) (SRO), a potential alternative buffer layer in coated conductors made by the inclined substrate deposition (ISD) method. Basic features of Raman microscopy are also discussed, and results are presented from a detailed Raman microprobe study of a 1.25-m-long YBCO coated conductor specimen produced at Oak Ridge National Laboratory (ORNL). Strain tolerance data are presented as a function of YBCO thickness for coated conductors with the standard ISD architecture.
