Abstract
Herein, the origin of flexomagnetic effect in Pb[(Zr0.52Ti0.48)0.60(Fe0.67W0.33)0.40]O3]0.80-[CoFe2O4]0.20 (PZTFW–CFO) multiferroic composite is demonstrated. An external inhomogeneous strain on thick composite films significantly changes the crystal lattice constants and phonon wave numbers related to single-phase PZTFW and CFO ceramics. Surface morphology indicates that inhomogeneous strain modified the magnetic dipole moments that partly regain their original position after removing external inhomogeneous strain. The magnitude of magnetic susceptibility increased under inhomogeneous strain for a small probe of the magnetic field. The magnetic anisotropic energy (MAE) supports that under-applied inhomogeneous strain reduces surface spin disorders and is responsible for the enhancement of zero field cooled (ZFC) and field cooled (FC) magnetization. Under a high external magnetic field (>100 Oe), it would be hard to detect the weak flexomagnetic effects. This work provides a framework for the effect of macroscopic inhomogeneous strain gradient on magnetic moments in multiferroics composites suggesting its suitability for the sensors and actuators applications.
