Paper Title:
Preparation and Study of Strong Magnetoelectric Coupling on Multiferroic BaTiO3/La0.7Sr0.3MnO3 Bilayer Heterostructure
  Abstract

The BaTiO3/La0.7Sr0.3MnO3((BTO/LSMO) bilayer films had been epitaxially grown on (001) oriented LaAlO3 (LAO) single crystal substrate by using pulsed laser deposition technique,. The measurements of electric and magnetic properties showed that the bilayer heterostructure possessed low dielectric constant (εr=263), high ferromagnetic curie temperature (Tc=317K), and natural ferromagnetic and ferroelectric properties. The magnetoelectric (ME) voltage coefficient for the bilayer heterostructures at room temperature was around 140 mV/cm.Oe, which is one magnitude order higher than others. The interface coupling parameter k between ferromagnetic and ferroelectric layers was 0.68.
