Elastic properties of ferrite nanomaterials: A compilation and a review

Abstract

The Poisson’s ratio, bulk modulus, Young’s modulus, and modulus of rigidity are elastic moduli frequently employed in engineering practice. In the industrial world, elastic data are used to assess material strength. When considering polycrystalline materials (such as spinel ferrites, superconductors, perovskites, and garnets) exposed to mechanical stresses, information on the material’s magnetic, electric, elastic, and dielectric properties aids in determining the material’s suitability for a given application. From the perspective of fundamental research, understanding elastic moduli clarifies the nature of forces (i.e., interatomic and interionic) in nanomaterials. Studies on a material’s elasticity play a significant role because they are crucial for determining the strength of its binding force. The computation of elastic moduli plays a very important role in overcoming physical stresses, especially in material fabrication and its industrial use. The present review focuses on the determination of elastic moduli using X-ray diffractometry and infrared spectroscopy.
