On the Cover

Self-assembled structures formed by magnetic microparticles in an oscillating magnetic field. The ring structure on the left is energetically more favorable than a chain (right) for more than four particles, but requires overcoming a potential barrier associated with chain bending. Clusters (middle) can form from two parallel chains with opposite polarizations.
