Abstract
The influence of magnetic (s = 1) and nonmagnetic (s = 0)
impurities in Y Ba2(Cu
M
O
, (M = Zn
and Co) system for x<0.01 were investigated by XRD, SEM, EDX, Resistivity,
Susceptibility and direct Critical Current measurements. Two methods of
doping have been used, namely, additional and substitutional. The XRD
results show no noticeable change in the crystal structure of our samples.
Doping the system with additional method did not result in a full
substitution of Co and Zn in the CuO2 plane. A very low percent
substitution of Zn and Co in YBCO system will be resided at the Cu (2) site
in the CuO2 planes.
Key words: Zinc substitution; Cobalt substitution; YBCO superconductors.
