Abstract
Multilayers consisting of the perovskite metallic oxides, ferromagnetic La2 /3Ba1/3MnO3 (LBMO) and paramagnetic LaNiO3 (LNO) have been grown by ozone-a ssisted molecular beam epitaxy. Structural characterization using in situ r eflection high-energy electron diffraction and high-resolution x-ray diffra ction reveal a very high degree of crystalline order. Magnetization and hys teresis measurements show evidence of antiferromagnetic coupling between LB MO layers when the LNO spacer is 15 A or less in thickness. (C) 1999 Americ an Institute of Physics.
