Nonlinear resistivity in fully oxygenate
✍ Dan Goldschmidt; Yakov Eckstein 📂 Article 📅 1992 🏛 Elsevier Science 🌐 English ⚖ 510 KB

Fully oxygenated ceramic YBa2Cu307\_6 has a non-linear resistivity [p (T) ] reminiscent of the resistivity Pb (along chains) in untwinned single crystals. The excess resistivity above 200 K, measured with respect to the linear portion of p(T) is activated. We suggest a Frenkel-disorder process, in w

A microscopic model is described which is able to reproduce the observed dependence of T¢ on oxygen stoichiometry for the 123 superconductor YBa2Cu3OT\_~. The approach provides a way of estimating the electron hole concentration at the planar copper sites and makes use of the expected location of th
