Abstract:

Structural transformations in dispersions of micron-sized iron particles suspended in a magnetite ferrofluid (the colloidal suspension of ferromagnetic nanoparticles in nonmagnetic liquid) are theoretically considered. An attempt is made to explain the tendency of iron particles to form doublets and longer chain aggregates with finite distance between particles in external magnetic field observed in recent experiments; in colloidal ferrofluid, micron-sized iron particles approach one another to finite distance that is equal approximately to the particle diameter. At moderate magnetic fields, minimal distance between approached particles is nearly independent of the strength of magnetic field. In ordinary magnetorheological dispersions, which are suspensions of magnetizing micron-sized particles in nonmagnetic liquid, the approach of particles practically does not occur up to their physical contact.
