Dielectric constant and ITC measurements of BaF2:Dy3+
Description
The ionic thermocurrents (ITC) are measured for BaF2:Dy3+. It is known that the rare earth (TR3+) associated with the interstitial ion (Fi-) of charge compensation forms a dipole. The ITC current and the dielectric constant measurements give interesting information about the dipole orientation (C3v) and their activation energy is obtained (E = 0.57 eV). It is possible to characterize the ionic conductivity induced by the Fi-ion migration (E' = 0.973 eV). (author)
