Abstract
A multifunctional material 0.65Ba0.955Yb0.025Er0.005TiO3–0.35CoFe2O4, owning superior piezoelectric, photoluminescence and magnetostrictive effects, was prepared via the conventional solid-state ceramic fabrication process. The ferroelectric, piezoelectric, dielectric, photoluminescence, as well as magnetic properties were characterized. Furthermore, in-situ magneto-electric, electro-photoluminescence and magneto-photoluminescence coupling effects were studied. A relatively larger magneto-electric coupling coefficient αE33 was determined to be 11 mV/Oe•cm@1 kHz, while the reversible electric and magnetic modulation ratio of integral intensity of green emission reached 16%@15 kV/cm and 2%@2 kOe, respectively. The underlying mechanism was discussed by PFM results, and the present work provides an alternative material to design devices with multiple functions.
