Dielectric and phonon spectroscopy of Nb-doped Pb(Zr1-yTiy)O3-CoFe2O4 composites
Original language description
A strong Maxwell-Wagner relaxation process dominates below 1 GHz due to the conductivity of CoFe2O4. Two additional relaxation processes are seen between 1 GHz and 1 THz. The lower-frequency one, coming from domain wall motion, disappears above TC ≈ 650 K. The higher-frequency component slows down on heating towards TC, because it is the central mode, which drives the ferroelectric phase transition. Similar temperature behavior of phonons as in the pure PZTN and CF was observed. Like in the pure Pb(Zr,Ti)O3, the soft phonon and central modes were also observed.
