Large magnetodielectric effect in nickel zinc ferrite-lithium niobate nanocomposite

► Porous nickel zinc ferrite-lithium niobate nanocomposite has been synthesized. ► The nanocomposites exhibit large magneto-dielectric coefficient of ∼20% at 300 K. ► It shows creep strain rate of 10−3 s−1 at 300 K indicating superplastic nature.
