Abstract
The high-Tc Y1-xNixBa2Cu3O7-δ samples doped by Ni for Y atom, with x=0, 0.002, 0.004, 0.006 and 0.01 were synthesized by the standard solid-state reaction method. The XRD diffraction of samples showed no impurity phase in all samples. Magnetic susceptibility of the samples under two different magnetic fields of 0.8 and 400 A/m was measured. The results showed that by increasing nickel element to an optimum value, the intragranular connection and flux pinning were improved.
