Effect of magnetic field on ferroelectric output voltage: a study on La 0.7 Sr 0.3 MnO 3 (LSMO)/P(VDF-TrFE) flexible multiferroic nanocomposite films

La 0.7 Sr 0.3 MnO 3 (LSMO)/poly(vinylidenefluoride-co-trifluoroethylene)(P(VDF-TrFE) particulate nanocomposite films prepared to produce large magnetoelectric (ME) voltage at room temperature for multifunctional device applications. LSMO nanoparticles (NPs) were prepared by sol–gel auto-combustion method and these NPs belong to space group R-3c. LSMO/P(VDF-TrFE) (0–3) nanocomposite (NC) films were prepared by solution casting method for different volume percentage of LSMO in P(VDF-TrFE). Dielectric and DC leakage current density(J) analysis of these NCs reveal very small loss tangents ( 0.01) and very small leakage current density J 10 −7 A/mm 2 respectively, which further demonstrate the uniform distribution of NPs in P(VDF-TrFE) matrix. Room temperature M-H and low temperature M-T analysis of LSMO NPs confirm ferromagnetic nature with Curie temperature at 368 K. LSMO/P(VDF-TrFE) NC films exhibit multiferroic properties up to 5
