Self-assembling behavior and interface structure in vertically aligned nanocomposite (PrBaMnO):(CeO) films on (001) (La,Sr)(Al,Ta)O substrates.

Heteroepitaxial oxide-based nanocomposite films possessing a variety of functional properties have attracted tremendous research interest. Here, self-assembled vertically aligned nanocomposite (PrBaMnO):(CeO) (x = 0.2 and 0.

B-site ordering and strain-induced phase transition in double-perovskite LaNiMnO films.

The magnetic and electrical properties of complex oxide thin films are closely related to the phase stability and cation ordering, which demands that we understand the process-structure-property relationships microscopically in functional materials research. Here we study multiferroic thin films of double-perovskite LaNiMnO epitaxially grown on SrTiO, KTaO, LaAlO and DyScO substrates by pulsed laser deposition. The effect of epitaxial strains imposed by the substrate on the microstructural properties of LaNiMnO has been systematically investigated by means of advanced electron microscopy.
