I propose a new type of magnetic spin reconstruction whereby a new symmetry appears on the near-surface of the material. As a consequence, there exists an associated magnetic ordering transition that occurs at a temperature lower than the bulk ordering temperature, a novel transition that has previously not been thought possible.

The phase diagram of a 2D model that exhibits the phenomenon is presented and shown to map to FCC lattices with nearest neighbour coupling. Materials expected to exhibit the reconstruction are discussed.
