EN

Artificial magnetic dipole arrays arranged on a square lattice exhibit a fascinating variety and complexity of configurations. Among the 16 possible configurations, six fulfill the spin ice rule of two dipoles pointing into a vertex and two point out. We present experimental realizations of magnetic dipole arrays and discuss the remanent state as well as the magnetization reversal in an external field.
