We report the fabrication of BiFeo(3)/BiCrO3(111) artificial superlattices with 1/1 stacking in a layer-by-layer growth mode on atomically flat SrTio(3)(111) surfaces. While BiFeo(3) and BiCro(3) are antiferromagnets having Fe-O-Fe and Cr-O-Cr bonds, these superlattices contain Fe-O-Cr bonds, in which ferromagnetic interaction is expected. Magnetization measurements at 300 K revealed that the magnetic moment per transition metal ion was 1.7 mu(B), suggesting ferromagnetic spin order. Ferroelectric behavior at room temperature was confirmed by an analysis using a scanning non-linear dielectric microscope. (c) 2008 The Japan Society of Applied Physics
