Structural characterisation on the nanoparticle doping of cerium (iv) oxide (ce02) into YBCO Superconductor / Afiq Awalludin

This report present the study of structural characterization on the nanoparticle
doping of Cerium (IV) Oxide (Ce02) into Yl-xCexBa2Cu30ɚ superconductor. The
samples with varying value' of Ce (x = 0.00, 0.02, 0.05, 0.10 and 0.20) were
prepared by using solid state method., The samples were characterized by using xray
diffraction (XRD). The peak shifting, lattice parameter and its orthorhombicity
were determined by using the data obtained from the XRD pattern. Pure sample (x
= 0.00) was observed to have the highest value of lattice parameter a, c and highest
unit cell volume which are 3.8491 A, 11.7385 A and 175.0778 A3 respectively.
Meanwhile, the lattice parameter b of pure sample were in between of samples
which have its x-value of 0.01 and 0.05. Generally, the trend of lattice parameter
for a, c and its unit cell volume decreases as the x-value increases whereas the lattice
parameter of b for each samples increases as the x-value increase. The XRD pattern
shows that all samples exhibit orthorhombic structure and peak at 28 = 32° is
shifted between [013] and [103] plane as the x-value increases.
