Keeping the formation of colloidal crystal under a centrifugal force in mind, we study the ordering of Brownian particles induced by a uniform external force. When the uniform external force is added, the particles move in the direction of the external force and the density of particles near walls becomes high. The ordering of particles starts on the walls, and successive ordering in bulk occurs near the walls. In bulk, both domains of the face-centered cubic structure and hexagonal close-packed structure appear. By controlling the direction and the strength of the external force, the number of ordered particles and distribution of cluster size are changed. © 2013 The Physical Society of Japan
