چکیده انگلیسی
The strong strain modulation of the magneto-resistance and electrical capacitance of the La0.85Sr0.15MnO3 film deposited on Si substrate is realized via the converse piezoelectric effect of 0.72â¯Pb(Mg1/3Nb2/3)O3-0.28PbTiO3 (PMN-PT) single crystal adhered on the thin Si substrate together. The modulation arises from the induced lattice strain in the La0.85Sr0.15MnO3 film, which is induced by the electric-field-induced strain in the piezoelectric crystal. When an external electric field is applied to the PMN-PT layer, the electric-ï¬eld-induced strain of the piezoelectric crystal will impose a compression strain on the film, subsequently resulting in an increase of the electrical resistance and electrical capacitance of the film. Under an electric field of â¼1â¯kV/cm, the electrical resistance of the film is enhanced â¼12.48% when the magnetic field is fixed on 0.2â¯T. The modulation mechanism which originates from the converse piezoelectric effect of piezoelectric material would be further extended to study the intrinsic strain of other oxide films.
