While most of the existing techniques applied for its assessment cannot be used to monitor the behaviour of ‘live’ systems in operando conditions, it is possible to use Electrochemical Immittance Spectroscopy (EIS) for this purpose. Nevertheless, analysis of these systems still requires an approximation made using transmission lines based models, which can be equated to specific diffusion elements parameters, which can in turn be related to qualities of the porous material investigated. The changes of these parameters can be correlated with various processes– such as dehydration and phase transitions or to the material’s processing history.

X-ray diffraction (XRD) analysis revealed favorable orthorhombicity values (~ 0.008) for the Y-123 crystal structure, and an estimated oxygen content close to the theoretical value (~ 6.8), along with the presence of light secondary phases such as Y2BaCuO5 (Y-211) and BaCuO2. For FESEM analysis, it was found that 5.0 wt.% Nd2O3 increased porosity and reduced grain size, negatively impacting superconductivity. Conversely, 0.5 wt.% Nd2O3 promoted significant grain growth, leading to enhanced grain contact and a denser microstructure. Electrical resistivity measurements confirmed superconducting transitions in all samples. Notably, the 0.5 wt.% Nd2O3 sample exhibited an optimal Tc-onset of 94.14 K with a narrow transition width ΔTc of 4.04 K. In contrast, the higher 5.0 wt.% Nd2O3 concentration resulted in a broader ΔTc of 7.47 K, suggesting the lower doping provided more optimal superconducting performance.
