Binary colloidal systems in two-dimensional circular cavities: Structure and dynamics†
Abstract
We study the melting behavior of a binary system (R = 4.5 μm, r = 2.8 μm) of paramagnetic colloidal spheres in two-dimensional (2D) circular cavities. A repulsive interaction between the particles is caused by an external magnetic field B that induces magnetic dipole moments perpendicular to the sample plane. By means of video
