High-pressure DC resistance of ZrO₂

Abstract

The resistance and thermoelectromotive force (TEMF) of Y₂O₃-stabilized ZrO₂ have been investigated in the pressure and temperature range between 15 and 50 GPa, and 77 and 400 K, respectively. At a pressure of about 35 GPa the resistance of the sample decreases by 3-4 orders of magnitude. At a pressure of about 42 GPa the anomalies in the pressure dependence of the resistance, TEMF and of the parameters which depend on the concentration, mobility, and activation energy of the charge carriers were found.
