Room temperature magnetoelectric and magnetodielectric properties of 2–2 bilayer 0.50Pb (Ni1/3Nb2/3) O3–0.35PbTiO3–0.15PbZrO3/CoFe2O4 thin film

Abstract A 2–2 bilayer composite 0.50Pb(Ni 1/3 Nb 2/3 )O 3 –0.35PbTiO 3 –0.15PbZrO 3 (PNNZT)/CoFe 2 O 4 (CFO) thin film has been fabricated using a pulsed laser deposition technique. Due to the coexistence of ferromagnetic (FM) order in the CFO layer and ferroelectric (FE) order in the PNNZT layer, the product property, i.e., the magnetoelectric (ME) coupling has been realized with a ME voltage coefficient (α E ) of ~500 mV/cm.Oe and a magnetodielectric response (MD(%) of 0.27 at room temperature. The present new composite thin film with its enhanced ME and MD properties could be a useful material for developing ME-based devices.
