Popis: Multilayers consisting of the perovskite metallic oxides, ferromagnetic La2/3Ba1/3MnO3 (LBMO) and paramagnetic LaNiO3 (LNO) have been grown by ozone-assisted molecular beam epitaxy. Structural characterization using in situ reflection high-energy electron diffraction and high-resolution x-ray diffraction reveal a very high degree of crystalline order. Magnetization and hysteresis measurements show evidence of antiferromagnetic coupling between LBMO layers when the LNO spacer is 15 A or less in thickness.
