Abstract

Broadband dielectric spectra from 10 to 10 ¹⁴Hz were acquired for 8 mol. % Y ₂O ₃/Yb ₂O ₃-stabilized zirconia (8YSZ and 8YbSZ) ceramics that related the dipole and ionic polarization losses to the absorption efficiency of electromagnetic irradiation. For 24 GHz irradiation, 8YSZ exhibited a higher absorption efficiency than 8YbSZ, resulting in a higher dielectric loss. The difference in the dielectric loss was interpreted as the difference in the loss of the dipoles originating from the fluctuations in the defect associations (Y′ _ZrVö and Yb′ _ZrVö).
