      abstract     = {The as-grown aged and thermally annealed at 720 K and 820 K
                      PbTiO3 crystals were prepared. The ɛ′(T,f) and σAC(T,f)
                      were measured at radio frequencies. Samples heated at 720 K
                      shown resistive switching to metallic-type σAC(T). The
                      resistivity switching was confirmed by RDC(T) measurement.
                      The samples annealed at 820 K were rejuvenated, exhibited
                      Curie-Weiss dependence above TC = 750 K and semiconductor
                      conductivity. Annealing induced changes in shape of the Pb
                      4f, Ti 2p, O 1s, and VB XPS lines. We propose a model
                      related to ionic migration toward FE domain walls and to
                      vortices which provide conducting channels.},
