“…The detailed growth procedure 149 was described previously [11]. One n × m = 3 × 4 SL was 150 prepared in moderately oxidizing conditions (MOCs) with an 151 oxygen pressure lower than 0.1 mbar, which is the oxygen 152 partial pressure normally used to grow optimally doped man-153 ganites [34].

The electronic properties of CaCuO 2 /La 0.7 Sr 0.3 MnO 3 (LSMO) superlattices are determined by the electronic structure of the structural units and in particular their interfaces. The electronic structure of LSMO is governed by a metal-insulator transition, which is controlled by the thickness of the units and the sample temperature, resulting in a systematic downward band shift for metallic samples (i.e., thick LSMO units, low temperature). We present a systematic study of the changes in the valence-band structure and screening features in Mn 2p and Cu 2p core-level spectra. The results show that hybridization of Cu 3d orbitals with out-of-plane O 2p orbitals can be systematically tuned by controlling the band alignment at the interface via the metal-to-insulator transition of the LSMO units. This opens a new route to rational design of functional interfaces and control of orbital reconstructions.

We have performed x-ray linear and circular magnetic dichroism experiments at the Mn L 2,3 -edge of the La 0.7 Sr 0.3 MnO 3 ultra thin films. Our measurements show that the antiferromagnetic (AF) insulating phase is stabilized by the interfacial rearrangement of the Mn 3d orbitals, despite the relevant magnetostriction anisotropic effect on the double-exchange ferromagnetic (FM) metallic phase. As a consequence, the Mn atomic magnetic moment orientation and how it reacts to strain differ in the FM and AF phases. In some cases a FM insulating (FMI) phase adds to the AF and FM. Its peculiar magnetic properties include in-plane magnetic anisotropy and partial release of the orbital moment quenching. Nevertheless the FMI phase appears little coupled to the other ones.

“…A viable means to reduce SOFCs operating temperature is to produce electrolytes in the form of thin films [2e4]. Pulsed laser deposition (PLD) is particularly promising amongst the different film deposition techniques because of its ability in reproducing complex target compositions onto the film [5]. Moreover, the deposition can be carried out at relatively low temperature values (z700 C) avoiding elemental interdiffusion at the substrate/film interface and preventing the detrimental formation of extra-phases at the electrolyte/electrode interfaces.…”

(LSGM) films with columnar structure were grown by pulsed laser deposition on (001) NdGaO 3 and SrTiO 3 buffered (001) MgO substrates. Combined analysis of the films structure and morphology and EIS measurements showed that the transport properties are mainly limited by perpendicular grain boundaries effects. Increasing the film thickness, columnar nanosized grains tend to coalesce leading to a decrease of grain boundary concentration, hence to enhanced conductivity. a r t i c l e i n f o
