Abstract
We report on getter annealed YBa2(Cu0.95Ni0.05)(3)O-y which are parama gnetic in a range from y = 6.1 to 6.8 with Curie-Weiss temperatures (T heta) remaining near 0 K. Reoxidation of the most reduced materials pr oduces superconductors with enhanced flux pinning followed in temperat ure by a paramagnetic range with unusually large negative Theta approx imate to -70 K indicative of Ni nanoclusters.
