Effect of magnetic field on ferroelectric output voltage: a study on La0.7Sr0.3MnO3 (LSMO)/P(VDF-TrFE) flexible multiferroic nanocomposite films

FEM modelling of magnetoelectric coupling in (2-2)LSMO/ P(VDF-TrFE) polymer composite

“…Up to a certain optimum field of HDC, λ saturates and becomes constant at higher HDC. As a result, the rate of change of λ with H becomes zero at higher HDC which diminishes the response of magnetic moments [25,17]. The generated strain in LSMO phase is passed to the elastically coupled P(VDF-TrFE) phase, which produces the elongation of the electric dipoles in the out-of-plane direction in P(VDF-TrFE).…”

“…Manganite shows excellent magnetostriction and double exchange mediated ferromagnetism at room temperature based on the phase diagram [15]. Among the ferromagnetic manganite compounds, La0.7Sr0.3MnO3(LSMO) has large volume magnetostriction (~10 -4 ), highest Curie temperature ~ 370K and excellent colossal magnetoresistance (CMR) properties [16,17]. ME properties of different LSMO based structures are also reported.…”

Magnetic field driven catalysis of multiferroic magnetoelectric nanocomposites

“…So far, the investigated magnetically-driven multiferroic nanomaterials for catalysis are mainly focused on the wellstudied CFO/BFO heterostructure system. The diversity of candidate magnetoelectric-catalysts needs to be further enriched, including other oxide-based nanocomposites [54][55][56]89,90] and polymer-based nanocomposites, [91][92][93] to promote the magnetoelectric coupling effect and improve the reaction kinetics by tuning the physical and chemical properties. Moreover, the emerging 2D materials with extraordinary physicochemical properties (e.g., high specific surface area, high charge mobility, and rich surface-active sites) hold great promise to serve as nanocatalysts for different catalytic applications.…”

“…In contrast, heterogeneous multiphase materials composed of ferromagnetic and ferroelectric phases can induce a piezo-magnetoelectric coupling effect between the electric and magnetic sub-systems at the interface. Up till now, well-designed composites have been developed as an intriguing alternative option for multiferroic materials, [29,51] as exemplified by CoFe 2 O 4 /BiFeO 3 , [52,53] Pb(Zr,Ti)O 3 /CoFe 2 O 4 , [54,55] Pb(Zr,Ti)O 3 /Fe 0.7 Ga 0.3 , [56] and La 0.7 Sr 0.3 MnO 3 /P(VDF-TrFE), [57] with strong magnetoelectric coupling that are orders of magnitude higher than in single phase. With the increasing demands for further miniaturization of electronic devices, the design and fabrication of nano-structured multiferroic composites is of great importance.…”

Self‐biased magnetoelectric composite for energy harvesting

“…Recently, SME response was observed in P(VDF–TrFE) ME polymer composite films filled with LSMO and LBMO (La 0.7 Ba 0.3 MnO 3 ) nanoparticles. The SME voltage of LSMO/P(VDF–TrFE) composites at 10 kHz and 25 Oe was 11.3175 mV (~151 mV cm −1 Oe −1 ), 108 which was higher than the SME voltage of 9 mV (~121 mV cm −1 Oe −1 ) of LBMO/P(VDF–TrFE) composites 109 . In summary, studies on the SME properties of rare‐earth manganese oxides mainly focus on ME thin films, and the main SME mechanism is derived from the exchange bias effect and the strain modulation effect.…”
