Nano-structuring technique can be an ultimate technique for realizing material development and device functionality because the nano meter is the same scale of the specific length relating to the collective systems for electrons, spins, charge, and so on, which determines physical properties. On the basis of the creation techniques originated from surface science, we have developed the original nanofabrication techniques, which enable the creation of the Fe3O4 epitaxial ultra-thin films and nanowires at a 10 nm length scale. Despite the high density of inevitable nanoscale defects, the ultrasmall Fe3O4 samples exhibit a prominent Verwey transition.
