Macroscopic and microscopic structural integrity in magnetic colloids-cationic micellar solution: Rheology, SANS and magneto-optical study

► This study exhibits zero field and field induced structural integrity between soft micelles and magnetic nanoparticles. ► The techniques used are viscosity measurements, Small Angle Neutron Scattering technique and magneto-optical birefringence. ► Study is useful for magnetic hyperthermia via micelles, as soft actuators, as an artificial micro-muscles, micro-manipulators, etc.
