A stimuli‐responsive material is synthesized that combines the actuation potential of liquid‐crystalline elastomers with the anisotropic magnetic properties of ellipsoidal iron oxide nanoparticles . The resulting nanocomposite exhibits unique shape‐memory features with magnetic information, which can be reversibly stored and erased via parameters typical of soft materials, such as high deformations, low stresses, and liquid‐crystalline smectic‐isotropic transition temperatures.
