Molecular Beam Epitaxy of Ferroic and Multiferroic Thin Films Figure 1A: Ji Cheng, G. Sterbinsky, B. W. Wessels, Sujing Xie and Vinayak P. Dravid Northwestern University Materials Research Science & Engineering Center Monica Olvera, Northwestern University, DMR 0520513 Fig 1A Epitaxial ferroic oxide thin films and multilayers have been synthesized by oxide molecular beam epitaxy (MBE), for combining materials with different properties such as ferromagnetism and ferroelectricity in a single structure. Fe3O4, CoFe2O4 and MgFe2O4 were deposited, which exhibit sharp interfaces with excellent cube-on-cube orientation. Magneto-optic Kerr effect (MOKE) and SQUID magnetometry measurements indicate that bulk-like magnetic properties can be obtained in the thin films.
