Abstract

Thin films of multiferroic double-perovskite La₂NiMnO₆ are prepared on (001)-oriented SrTiO₃, (La_0.289Sr_0.712)(Al_0.633Ta_0.356)O₃, and LaSrAlO₄ substrates by pulsed laser deposition. Microstructure investigation by advanced electron microscopy shows that the La₂NiMnO₆ films have a monoclinic structure on the SrTiO₃ substrates and a rhombohedral structure on the (La_0.289Sr_0.712)(Al_0.633Ta_0.356)O₃ and LaSrAlO₄ substrates. Atomic-scale elemental maps of the monoclinic and rhombohedral phases reveal a short-range and/or partial ordering of the B-sites. In addition, domains and columnar grains are found in the films. Our results demonstrate that the phase and microstructure of the La₂NiMnO₆ films can be tuned by epitaxial strains induced by different substrates.
