Abstract
This report describes the magnetoelectric multiferroic property of Mn0.5Cu0.2Zn0.3Fe2O4 (MCZF) nanofillers embedded PVDF nanocomposite films. The crystallographic phases were confirmed by XRD analysis. MCZF nanofillers inside PVDF were observed in FESEM micrographs. The presence of the magnetic ordering in MCZF-PVDF films and its variation by altering the weight percentage of MCZF-nanofillers in PVDF matrix was found. Nonlinear nature of P-E loop of MCZF-PVDF films clearly indicates room temperature ferroelectric ordering in MCZF-PVDF films. A clear transition from ferroelectric to paraelectric behaviour was also observed in the MCZF-PVDF films. The dielectric response with change in static magnetic field was investigated to show the presence of coupling between magnetic and ferroelectric orderings. These results confirm the presence of type-II multiferroic behaviour owing to the magnetostrictive and piezoelectric phases in MCZF-PVDF films. This novel magnetoelectric multiferroic property of MCZF-PVDF laminated nanocomposite films is very much useful for various device applications.
