Magnetoelastic materials is the academic concept and research area dedicated to understanding and utilizing materials that exhibit magnetoelastic coupling, a phenomenon where magnetic properties are intrinsically linked to elastic (mechanical) properties. This field investigates the reciprocal effects, such as dimensional changes induced by magnetization (magnetostriction) and alterations in magnetic characteristics under mechanical stress or strain. Its significance is evidenced by contributions to optimizing high-density magnetic recording media, developing smart materials, and advancing nanotechnology.
