Abstract:

Magnetoelectric (1−x) BNT−x CFO nanoparticulate thin films with (x = 0, 0.1, 0.2, 0.3) were fabricated by a chemical solution deposition technique. The X-ray diffraction shows that no other secondary phases are observed. Transmission electron microscope (TEM) revels that CFO nanoparticles were well distributed in matrix of BNT. The nanocomposite films exhibit both good magnetic and ferroelectric properties at room temperature (R-T), as well as enhanced magnetoelectric coupling. The composite with x = 0.2, showed the large value of ME voltage coefficient (αE ) ~ 163 mV/cmOe. These ME composites provide a great opportunity as potential lead free systems for ME devices.
