Nd-laser irradiations effects and AFM-investigations on structural and surface features of optimally lutetium thorium-co-doped-2212-BSCCO

► Optimally co-doped Lu-Th-superconductor sample crystallized in tetragonal phase 2212-BSCCO. ► The fingerprint of both structures experimental and theoretical are nearly identical. ► The average grain size in different spots inside the sample found in between 0.35 and 1.45 μm. ► After maximum Nd-laser irradiation dose the morphology of the surface is directed and oriented. ► The Tc-onsets of the optimally co-doped Lu-Th-sample increase as irradiation power and duration time increases.
