Interplay between the ferrimagnetic and ferroelectric phases on the large magnetoelectric coupling of x Li 0.1 Ni 0.2 Mn 0.6 Fe 2.1 O 4 –(1 − x )Bi 0.8 Dy 0.2 FeO 3 composites

The multiferroic composites of ferromagnetic Li 0.1 Ni 0.2 Mn 0.6 Fe 2.1 O 4 (LNMFO) and ferroelectric Bi 0.8 Dy 0.2 FeO 3 (BDFO) with the general formula x Li 0.1 Ni 0.2 Mn 0.6 Fe 2.1 O 4 –(1 − x ) Bi 0.8 Dy 0.2 FeO 3 have been prepared by the solid-state reaction route. The XRD analysis has ensured that the composites are composed of a mixture of cubic spinel LNMFO and orthorhombic perovskite BDFO phases. Field Emission Scanning Electron Microscope is used to investigate the surface morphology of the studied compositions. The average grain size of the composites has reduced slightly with the enhancement of ferrite part up to 20
