Magnetic Properties and Electric-Field Modulation Effect in La-Ca-MnO3 Based Magnetoelectric Composite
Bulk La0.6Ca0.4MnO3 (named as LCMO) and LCMO/Pb (Zr0.52Ti0.48)O3 (PZT) thin film were prepared by sol-gel method and spin coating technology. The crystal structure, magnetic properties and magnetoelectric effect were measured. The experimental results indicate that, due to the change of crystal lattice interaction and the different coupling states between magnetic atoms, the Curie temperatures (Tc) of the two samples are very different. Furthermore, the effective modulation effects of the electric field on Tc, as well as the magnetization of LCMO/PZT composite, were ob-tained by an electric field applied to the ferroelectrics. The investigation shows that, besides magnetic field, the static electric field can also be used to modulate the magnetic properties, which increases the degree of freedom of the manipulation in functional materials, and therefore may realize the multifunctional properties of materials.
