Doping Effect and I (V) Characteristic as Found by E.S.R.
The macroscopic effect of doping on the clectrical characteristic I(V) of varistors is well known,but, its microscopic mecanism is not yet clearly understood. So, we have performed E.S.R. measurements in ZnO-Bi2O3 systems doped with paramagnetic oxides. Informations are drawn from E.S.R and electrical conductivity data.
