Ni–Cr textured substrates with reduced ferromagnetism for coated conductor applications

Abstract 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. The magnetic properties were investigated, including the hysteretic loss in a Ni–7at.%Cr sample that was controllably deformed; for comparison, the loss was also measured in a similarly deformed pure Ni substrate. Complementary X-ray diffraction studies show that thermomechanical processing produces nearly complete {1 0 0}〈1 0 0〉 cube texturing, as desired for applications.
