Characterization of a strongly textured non-ferromagnetic Cu-33 at%Ni substrate coated with a CeO_2 buffer layer

摘要

The microstructure, crystallographic texture and magnetic properties have been studied in a Cu-33 at%Ni substrate produced by cold rolling to a reduction of ～99% with subsequent annealing at 1000 C for 1 h in a protective atmosphere. This treatment results in a strongly textured material, where the fraction of the cube {001} <100> texture is 99.8% and the fraction of boundary misorientations with angles greater than 10° is only 5%. The material is shown to be non-ferromagnetic at typical operating temperatures for coated conductors. Furthermore, it is shown that a CeO_2 buffer layer can be successfully deposited on the Cu-33 at%Ni substrate using dip-coating.
