“…It is much smaller than the typical activation energy (~1000 meV) of ions, oxygen vacancies and/or dipoles in oxides. For instance, the activation energy of oxygen vacancies is 910 meV for BaTiO 3 22 , 1005–1560 meV for KNbO 3 30 , and 1030 meV for YBCO ceramics 31 . Liu et al .…”

“…Several groups have performed anelastic measurements employing different techniques to investigate oxygen migration (and defects) in YBa 2 Cu 3 O y (Y123) [1][2][3][4][5][6][7][8][9][10][11] and RBa 2 Cu 3 O y (R123, R = rare earth) [12][13][14][15]. Oxygen migration behavior in R123 is considerably influenced by the ionic size of the rare earth ion [12][13][14].…”

“…), superlaidininko sluoksniui esant kambario temperatūroje ir inertinių dujų apsuptyje. Sąveikaudamas su lazerio spinduliuote superlaidininkas įkaito daugiau kaip = T 670 K temperatūros, kuri literatūroje įvardyta Y-Ba-Cu-O medžiagos fazinio virsmo iš ortorombinės į tetragoninę kristalinę struktūrą temperatūra (Xie et al 1989). Lazerio šviesa paveiktos plono sluoksnio sritys prarado deguonį (t. y. x > 0,6 iš YBa 2 Cu 3 O 7-x ) ir tapo nesuperlaidžiomis netgi, kai T << T c on .…”
