Suzuki We have found ferromagnetism in epitaxially grown superlattices of CaRuO 3 /CaMnO 3 that arises in one unit cell at the interface. Scanning transmission electron microscopy and electron energy loss spectroscopy indicate that the difference in magnitude of the Mn valence states between the center of the... [Phys. Rev.
