A multilayer film of BiFeO3∕La0.7Sr0.3MnO3∕SrTiO3 was deposited on Si substrate by pulsed laser deposition method, in which La0.7Sr0.3MnO3 was used as a bottom electrode. X-ray diffraction showed that the film was polycrystalline. From the x-ray photoelectron spectroscopy measurement, the valence number of the Fe ion was found to be 3+. The BiFeO3 film showed a low leakage-current density, and a large twice remanent polarization (2Pr) of 110μC∕cm2 was observed at room temperature. Owing to the ferromagnetic and magnetostrictive properties of La0.7Sr0.3MnO3, this multilayer film system is a promising candidate for the study of magnetoelectric coupling.

We have studied the magnetic and magnetoresistance properties in polycrystalline Ni50−xCoxMn32Al18 Heusler alloys. A unique martensitic transformation (MT) from the ferromagnetic austenite to the weak-magnetic martensite phase was obtained and magnetic-field-induced reverse MT was confirmed in these alloys. A magnetic difference up to 45 emu/g was measured across the MT for Ni42Co8Mn32Al18 alloy. In the same quaternary alloy, the large magnetoresistance effect of 67% at 225 K was observed through this field-induced magnetic phase transition.
