Self-assembled Co dot chains were epitaxially grown on Ru(0001) along grooves and were characterized with atomic- and magnetic-force microscopies, and the-magneto-optic Kerr effect. The dots are of order 100 nm in diameter and 1-7 nm high and have magnetic single domains with in-plane uniaxial anisotropy along the grooves. The interdot pair correlation along a chain was deduced experimentally from the magnetic-force microscopy images, and can be understood in terms of the classical one-dimensional Ising model.
