Abstract

Composites are a class of materials which provide a scope of tailoring properties that are not possible amongst its constituents. Magnetoelectric composite materials exhibit product property arising because of mutually connected electric and magnetic phases. The systematic and comprehensive study on structural, tunable dielectric and flexible energy storage study of NdMnO3 (ND) manganite-based composites has been reported. The phase purity is estimated X-ray diffraction studies and confirm composite formation. The dielectric studies display a step-like decrease and reveal Maxwell-Wagner polarization with relaxation processes. The effect of magnetic field on dielectric constant reveals strong variation due to modification of spatial charge distribution. The qualitative evidence of tunable energy storage studies in ND based composites is observed by measuring the ferroelectric P-E hysteresis loop in variable magnetic field and is strain originated from coupling amongst individual component phases.
