Polarizable colloids are expected to form crystalline equilibrium phases when exposed to a steady, uniform field. However, when colloids become localized this field-induced phase transition arrests and the suspension persists indefinitely as a kineti

When exposed to a magnetic field, paramagnetic colloidal particles acquire dipole moments. Interaction between induced moments leads to the formation of different microstructures that depend on the strength and characteristics of the external magneti
