Epitaxial NiO-Co exchange-biased bilayers grown on MgO single crystals Influence of the substrate orientation on the film morphology, the Co structure and the magnetic behavior
Co/NiO bilayers have been grown on MgO(001), MgO(110) and MgO(111) substrates in an ultra high vacuum sputtering chamber. Growth mode and surface morphology are investigated by X-ray diffraction, Reflection Hi...

TEM study of nanostructured BZO templates in (001)-LAO and (001)-STO substrates for the growth of superconducting YBCO films
A methodology for the preparation of artificially nanostructured oxide templates by means of chemical solution deposition has already been reported elsewhere [1]. A fine tuning of nanodots’ size, morphology an...

Phase segregation leading to spontaneous outcrop** of (Sr,La)Ox dots in La1−xSrxMnO3 films
La1−xSrxMnO3 (LSMO) with x=0.3–0.4 exhibits metallic ferromagnetism at room temperature and offers good lattice mismatch with YBCO. Such properties bring LSMO an interesting potential as template for the growth o...

Synthesis of Cobalt Nanoparticles, Nanorods and Nanowires assisted by Oleic Acid and Oleylamine based Mixtures.
In this paper we report on the synthesis in solution of cobalt nanoparticles, nanorods and nanowires achieved through the decomposition of an organometallic precursor Co(?3-C8H13)(?4-C8H12) and stabilized by carb...

Fine Structure of Sputtered Ni/Ti Multilayered Thin Films Studied by HREM
Ni/Ti multilayered thin films can be efficient neutron guides and are therefore of great interest in neutron optics. Ni/Ti and NiC/Ti multilayers with various layer thicknesses were fabricated by magnetron spu...

Effect of Ion Irradiation on the Artificial Structure and the Interlayer Coupling of Copper-Cobalt Multilayers
Structural defects like local ferromagnetic short-circuits are responsible for large reductions of the intrinsic interlayer coupling in the case of antiferromagnetically (AF) coupled multilayers (ML). We have ...

Influence of the Partial Substitution of Small Rare Earths for Ca in the Superconductive Bi-Sr-Ca-Cu-O Compound
Superconductive 2:2:1:2 phases of the type Bi2Sr2Ca1-yLnyCu2O8+x+y/2, where Ln stands for Yb or Er, have been synthesized and characterised by X-ray and electron diffraction. The small rare earth atoms prove to s...
