Magnetoelectric materials have attracted considerable attention for several decades owing to their both magnetic and electric properties. The magnetoelectric multilayer, Ba0.5Sr0.5TiO 3/CoFe2O4, has been fabricated by the aid of pulsed laser deposition technique and after fabrication characterized by X-ray diffraction pattern and magnetoelectric effect. Sufficient magnetoelectric coefficient has been observed in samples with increasing biased magnetic field. Our results suggest that magnetoelectric coupling effect may be tuned by interlayer properties and biased magnetic field which show the capability of use in nonvolatile memory, phase shifter, and sensor applications. © 2013 Springer Science+Business Media New York.

We report an experimental study on the effect of Ag nanoparticles on the polar magneto-optical Kerr effect in cobalt thin film. The magneto-optical cobalt thin film was prepared by electron beam deposition method onto the Ag nanoparticles which were synthesized by laser ablation in liquid technique. Our results indicate that we have sufficient enhancement of polar magneto-optical Kerr effect of cobalt thin film around the surface plasmon resonance of Ag nanoparticles. Moreover, combination of surface plasmon resonance of the Ag nanoparticles and very thin Au layer can be attained the enhancement factor in all of visible spectral region. © 2013 Springer Science+Business Media New York.
