Figure 3.

a and b Complex impedance plots of the nanocrystalline GDC0.2 and EuDC0.2 at 300°C. GI and GB correspond to the grain interior and grain boundary, respectively; c and d are the complex impedance plots of DyDC0.2 and HDC0.2 at 400°C. Symbols are the obtained data points, and solid semicircles are the fitted data
