TL;DR: In this paper, a systematic study of the influence of various in situ annealing parameters shows an optimum temperature of about 600°C in a background of 0.7 atm of Ar/4%H 2 for layers consisting of a mixture of magnesium and boron.

TL;DR: In this paper, the authors show that oxypnictide superconductors exhibit substantial electromagnetic granularity on a scale approximating the grain size, though they cannot yet determine whether this is intrinsic or extrinsic.

TL;DR: In this article, a systematic study of the influence of various in-situ annealing parameters shows an optimum temperature of about 600C in a background of 0.7 atm.

TL;DR: In this article, the authors summarized the current status of basic research related to the understanding and development of coated conductor tapes for use in large scale superconducting applications and reported highlights of a workshop and discussion meeting which dealt with many of the central issues associated with both thick film deposition methods and the defects that control the critical current densities.

TL;DR: A series of biaxially textured Ni1−xCrx materials, with compositions x=0, 7, 9, 11, and 13 at.%Cr, have been studied for use as substrate materials in coated conductor applications with high temperature superconductors as discussed by the authors.
