A novel concept of enhancing the magnetostrictive strain of sintered cobalt ferrite by making self-composites from nanosized and bulk powders with different particle sizes of the same material as components is reported. The self-composites give higher magnetostriction coefficient and strain derivative when compared to the sintered products obtained from the individual powders. The individual components give a maximum magnetostriction up to similar to 310 ppm, whereas up to similar to 370 ppm is obtained for a two-component system consisting of powders of two different sizes. On the other hand, a three-component self-composite made from starting powders of 3 nm, 40 nm and &gt;1 mu m give very high magnetostriction of similar to 400 ppm at 800 kA/m, suitable for making devices.</p>10aCobalt ferrite10aMagnetostriction10aNanocrystalline10aself-composite10aSintering1 aMohaideen, Kamal, Khaja1 aJoy, Pattayil, Alias  uhttps://library.ncl.res.in/content/enhancement-magnetostriction-sintered-cobalt-ferrite-making-self-composites-0
