The interaction between the magnetic environment and a wide range of soft matter, including colloids, polymers, surfactants, liquid crystals, emulsions, biomaterials, and disordered systems, provides an important opportunity to understand the underlying physical properties of the structures, dynamics, and functions in these systems. More importantly, this interaction has made it possible to develop some of most advanced technologies (such as magnetic resonance imaging, magnetic force microscopy, and magnetic resonance force imaging), that benefit not only the scientific community but society generally. This focus session will explore the following two aspects: 1) effect of magnetic field on soft matter, and 2) the importance of magnetism in modern technology in interdisciplinary areas. Both experimental and theoretical work are solicited. Abstracts in the following areas are welcome:
