Abstract
The piezoelectric deformation of a commercial Pb(ZrxTi1-x)O-3 ceramic has been measured down to 0.4 K. The length relaxation (or creep) orig inated by a change in the applied electric field, has been followed fo r seven decades of time. Extrapolation of our results shows that this relaxation does not disappear at 0 K. That is indicative that nonactiv ated processes are responsible for the piezoelectric relaxation near O K.
