MAGNETIC PROPERTIES OF BIAXIALLY ORIENTED NI-V SUBSTRATE

The paper presents the structural and magnetic properties of a new non-magnetic biaxially textured substrate based on Ni100-xVx solid-solution for YBa2Cu3O7-y tape fabrication. The effective atomic magnetic moment monotonously decreases with the vanadium concentration, causing a corresponding decrease of Curie temperature. The Curie temperature reaches the zero value at about 11.5. % of vanadium. The texturing studies revealed that (100)[001] cube texture can be easily developed up to x=11 at. %, by a cold rolling process followed by a recrystallization thermal treatment. The X-ray ω and ϕ scans have demonstrated that the samples have a good out-of-plane and in-plane texture for the whole solubility range, with FWHM of 7° and 11°, respectively. The correlation between the magnetic and structural anisotropy was also studied.
