The effect of the partial substitution of La by Gd atoms on the magnetic entropy change of the LaFe 11.4 Si 1.6 metamagnetic compound was studied using Mossbauer spectroscopy and DC magnetization measurements. A considerable enhancement of the magnet

Magnetic properties of zero field cooled (ZFC) and field cooled (FC) sample of (Mn,Fe) 2 O 3− t nanograins have been investigated by magnetometry (up to 70 kOe) and Mossbauer spectroscopy (up to 60 kOe) in the temperature interval 4.2–300 K. Larg

We report on polarized X-ray absorption spectroscopy (P-XAS) study of La 0.7 Sr 0.3 MnO 3 (LSMO) films, epitaxially grown by laser ablation on tensile (SrTiO 3 ) and compressive (LaAlO 3 ) substrates. In-plane and out-of-plane bond information was ob

Ferromagnetic manganite films (La0.7Sr0.3MnO3 (LSMO) and La0.7Ca0.3MnO3 (LCMO)) have been deposited on lattice-mismatched perovskite single-crystalline substrates. Strained epitaxial growth is obtained using the pulsed laser deposition (PLD) techniqu

La0.7Sr0.3MnO3 is predicted to show half-metallic behaviour at low temperature, which gives rise to a metallic character for one spin direction and an insulating character for the other. This 100% polarisation of the conduction band should enhance th

We report on an angular resolved x-ray absorption spectroscopy study of the local atomic structure around the manganese ions in La0.7Sr0.3MnO3 thin films epitaxially grown on tensile and compressive substrates. Ab initio calculations provide strong s

We report here on an X-ray absorption study of La 0.7 Sr 0.3 MnO 3 films epitaxially grown on SrTiO 3 substrate. The local organization around Mn in oriented films with 600 A in thickness was investigated by polarized Extended X-ray Absorption Fine S

We report on Mn K‐edge X‐ray absorption study, in plane and out of plane, of La0.7Sr0.3MnO3 films, epitaxially grown on a tensile substrate SrTiO3 by laser ablation. From Extended X‐ray Absorption Fine Structure in the film plane we observe a s
