Abstract
A four point Hebb-Wagner type polarization method is described. It all ows (a) an accurate determination of the partial electronic conductivi ty of a mixed ionic electronic conductor, MIEC, and (b) a check on whe ther the ionic partial current is really suppressed. Measurements on C uBr show that it decomposes and that the ionic current is dominant. Do ping CuBr reveals that CuBr is an n-type MIEC.
