Abstract Anelastic spectra (elastic energy absorption as a function of temperature) are reported which provide evidence that excess O in La 2 CuO 4+ δ starts forming two different types of defects already at very low concentrations, where no phase separation or changes in the type of O intercalation are believed to occur. The absorption peak with the lowest activation enthalpy, H / k B =5600 K, is visible at lowest values of δ and is attributed to the hopping of single interstitial O 2− ions… CONTINUE READING
