Ferromagnetic 1D oxide nanostructures grown from chemical solutions in confined geometries

Abstract

This review summarizes the capabilities and recent developments of nanoporous polymeric template systems directly supported on different substrates for the confined growth of epitaxial ferromagnetic complex oxide 1D nanostructures. In particular, we describe the versatility and potentiality of chemical solutions combined with track-etched polymers to synthesize (i) vertical polycrystalline La_0.7Sr_0.3MnO₃ nanorods on top of single crystal perovskites, (ii) single crystalline manganese based octahedral molecular sieve (OMS) nanowires on silicon substrates, and (iii) the epitaxial directional single crystal OMS nanowires on top of fluorite-type substrates. The influence of the distinct growth parameters on the nanostructural evolution of the resulting nanostructures and their magnetic properties is further discussed in detail.
