“…Nanostructure growth La 0:7 Sr 0:3 MnO 3 nanoislands were obtained following the CSD route from precursor solutions prepared by dissolving metal propionates in the stoichiometric ratio in propionic acid. 19 Solution concentrations of 0.03 M (with respect to the Mn cation) were used. The metalorganic solution was deposited on 5 Â 5 mm 2 fluorite-structure (001)-YSZ single crystal substrates and spin-coated at 6000 rpm for 2 min.…”

Strain-induced self-assembled La 0:7 Sr 0:3 MnO 3 nanoislands of lateral size 50À150 nm and height 10À40 nm have been grown on yttria-stabilized zirconia (001)-substrates from ultradiluted chemical solutions based on metal propionates. The nanoislands grow highly relaxed withstanding the epitaxial relation 001 ð Þ LSMO 110 ½ == 001 ð Þ YSZ 010 ½ and show bulk-like average magnetic properties in terms of Curie temperature and saturation magnetization. The interplay of the magnetocrystalline and shape anisotropy within the nanoisland ensemble results in an in-plane magnetic anisotropy with a magnetocrystalline constant K 1 150 K ð Þ¼À 561 ð ÞkJ=m 3 and in-plane easy axis along the 110 ½ ÀLa 0:7 Sr 0:3 MnO 3 direction as measured, for the first time, through ferromagnetic resonance experiments. Magnetic force microscopy studies reveal the correlation between nanoisland size and its magnetic domain structure in agreement with micromagnetic simulations. In particular, we have established the required geometric conditions for single domain, multidomain, and vortex configurations.

Abstract:Ferroelectric BaTiO 3 (BTO) as well as ferromagnetic La 0.7 Sr 0.3 MnO 3 (LSMO) thin films were prepared by chemical solution deposition (CSD). Based on these, a multiferroic architecture stack of La 0.7 Sr 0.3 MnO 3 / BaTiO 3 layers was developed. Aqueous, environmentally friendly precursor solutions were formulated for both materials. These are used for ink plotting on SrTiO 3 (100) substrates. Films were subjected to a subsequent thermal treatment at the corresponding crystallization temperature. The structural as well as the magnetic and electric properties are presented. The Curie temperature of the ferromagnetic LSMO layer with a film thickness of only 100 nm was determined to 360 K. The magnetization curve indicates a hysteresis loop with a saturation magnetization of 280 emu/cm 3 . The ferroelectric character of BTO films was demonstrated by polarization curves.

“…LSMO nanoislands on (001) oriented MgO substrates were obtained by CSD from solutions of the metal propionates in propionic acid 6 and subsequent annealing at 900 C under oxygen atmosphere for 1-3 h. Fig. 1(a) is an atomic force microscopy (AFM) image, obtained in the dynamic mode, of the LSMO nanodot-decorated (001)-MgO surface, showing homogeneous spatial and size distributions.…”

“…8 Close inspection of the fine structure of the {101}-LSMO-poles (see inset in Fig. 2(a)) reveals that each pole is associated to four satellites lying along the [110] and [1][2][3][4][5][6][7][8][9][10] directions, indicating the occurrence of four additional orientation domains related to the precise cube-on-cube orientation by 2 to 5 tilts about the [110] and [1][2][3][4][5][6][7][8][9][10] axes. In order to determine the average in-plane strain state of the nanodots ensemble, we conducted XRD / -2h/x space mapping (/ is the azimuthal orientation) at a grazing incidence angle of 0.…”
