A ferromagnetic shape memory alloy was utilized to construct a Ni43Mn41Co5Sn11/Pb(Zr,Ti)O3 laminate. Large direct and converse magnetoelectric (ME) effects were observed at resonance frequencies around the martensitic transition temperature of Ni43Mn41Co5Sn11 alloy, and the temperature affects the ME properties remarkably. The ME coefficients respond almost linearly to the applied ac electric or magnetic field. The mechanism of both direct and converse ME effects in the laminate is discussed.

The effects of electric field on the magnetization and Hall resistivity were investigated in a laminated composite consisting of polycrystalline perovskite La2/3(Ca0.6Ba0.4)1/3MnO3 (LCBMO) material and Pb(Zr0.52Ti0.48)O3 (PZT) ferroelectric ceramic. Upon applying an electric field (9 kV/cm) on the ferroelectric ceramic, the Hall resistivity change of the LCBMO layer is up to − 23%. The electric field-modulated Hall resistivity in LCBMO/PZT composite is attributed to the coaction of magnetization change and carrier concentration change, which result from stress-induced variation of both metal–insulator transition and ferromagnetic–paramagnetic transition.

We demonstrate that ferroelectric (FE) domain switching induces a nonvolatile tuning of the magnetic and electric properties in La<sub>0.6</sub>Ca<sub>0.4</sub>MnO<sub>3</sub> (LCMO)/Pb(Mg<sub>1/3</sub>Nb<sub>2/3</sub>)O<sub>3</sub>-PbTiO<sub>3</sub> heterostructure. The FE domain switching in the substrate contributes to an in-plane strain that changes the spin exchange coupling in the LCMO layer, and therefore results in a nonvolatile magnetization difference of up to -17.5% at zero external magnetic field, as well as a nonvolatile resistance difference of up to 20.3%. This nonvolatility of the modulation effect on the magnetic and electric properties by an electric field demonstrates great potential for the applications of magnetic and electric devices.

As one typical example of third-generation thin-film solar cells, Dye-sensitized Solar Cell (DSSC) has become a research hot-spot because of its advantages. As a basic electron transport material, the modification of the nano-crystalline TiO2 would have remarkable influence on the cell. In this work, the scattering layer was firstly fabricated on the conductive glass substrate by sol–gel dip-coating method for the stable and high efficiency conventional DSSC. And the effect of the modification of the nanocrystalline TiO2 photoanode by the tetrabutyl titanate sol was investigated. Practically, the cell with photoanode modified by tetrabutyl titanate sol obviously presents higher light-electric conversion efficiency.

We investigated the effects of electric field on the magnetization and electric transport properties in La0.6Ca0.4MnO3/Pb(Zr0.52Ti0.48)O3 (LCMO/PZT) thin film prepared by sol-gel method and simple spin coating technology. Obvious converse magnetoelectric effect (the relative change in magnetization, ΔM ∼ 15%), as well as large electroresistance effect (the relative change in resistance, ER ∼ 61%), has been obtained in LCMO thin film with applying electric field on the PZT ceramic. The efficient mechanical coupling, which originated from ferroelectric polarization and inverse piezoelectric effect in PZT substrate, leads to large changes in the magnetism and resistance of LCMO thin film. The experimental results can be interpreted by the changes of both spin exchange coupling and electron-lattice coupling strengths in LCMO film, which result from the strain at the ferromagnetic/ferroelectric interface.

Recently, much attention have been drawn to converse magnetoelectric(CME) effect, as well as electric field modulated transport properties in magnetoelectric heterostructure composites. In situ Electric field (E) modulating magnetic and electric transport properties have be well achieved in magnetoelectric bilayer films. These excellent investigations open a new pathway to the electronic control of magnetism and other properties in strong-correlated oxide materials. In this paper, we investigate the manipulation effect of polarization switching induced by ex situ E on the magnetic and electrical properties of La0.6Ca0.4MnO3 (LCMO) thin film grown on the Pb(Mg,Nb)O3-PbTiO3 (PMN-PT) single-crystal substrate by pulsed laser deposition(PLD).

La2/3(Ca0.6Ba0.4)1/3MnO3/XNiO heterogenous composites have been synthesized by modified sol-gel method. Resistivity versus temperature in difference magnetic fields for the samples, as well as magnetoresistance (MR) versus magnetic in room temperature, have been measured. It is indicated that the addition of NiO results to the increase in resistivity and the weakeness in magnetization. Enhanced MR has been obtained in NiO-doped composites. The temperature dependence of magenetoresistance for NiO-doped composites in low magnetic field may be explained by the model of spin-polarized tunneling. The vary trend of MR in MR-T curve is similar to the result obtained by Monte Carlo simulation. MR in high magnetic field may be explained by spin polarization inside ferromagnetic grains.
