KrF pulsed laser deposition of La5Ca9Cu24O41 thin films on various substrates
(2009)
Recent studies on single crystals of cuprate oxides containing spin chains and ladders have reported large anisotropic magnon-mediated thermal conductivity. A potential use of thin films of such materials could be in the ...
PLD of Fe3O4 thin films: Influence of background gas on surface morphology and magnetic properties
(2006)
Ablation of Fe3O4 targets has been performed using a pulsed UV laser (KrF, λ = 248 nm, 30 ns pulse duration) onto Si(100) substrates, in reactive atmospheres of O2 and/or Ar, with different oxygen partial pressures. The ...
Synthesis and characterization of Cr-B-N coatings deposited by reactive arc evaporation
(2008)
Nanocomposite Cr-B-N coatings were deposited from CrB0.2 compound targets by reactive arc evaporation using an Ar/N2 discharge at 500 °C and -20 V substrate bias. Elastic recoil detection (ERDA), x-ray photoelectron ...
Magnetic properties of Fe3O4 thin films grown on different substrates by laser ablation
(2007)
Magnetite thin films have been grown onto (1 0 0)Si, (1 0 0)GaAs and (0 0 0 1)Al2O3, at substrate temperatures varying from 473 to 673 K, by UV pulsed laser ablation of Fe3O4 targets in reactive atmospheres of O2 and Ar, ...
Principles of Cerebral Ultrasound Contrast Imaging
(2009)
Ultrasound contrast is gaining acceptance worldwide as an adjunct to conventional ultrasound imaging. It has clinical applications as diverse as liver disease detection and characterization, myocardial perfusion and wall ...
LaSrMnCoO6: A new cubic double perovskite oxide
(2003)
Single-phase polycrystalline powder samples of the double perovskite oxide LaSrMnCoO6 were synthesized by the Pechini (citrate-gel) technique. The structural, magnetic and electrical properties of the obtained powders were ...
Realization of La2MnVO6: Search for half-metallic antiferromagnetism?
(2002)
Single-phase polycrystalline La2MnVO6 samples were synthesized by arc-melting and characterized by X-ray diffraction, magnetization and resistivity measurements. We find that the compound has cubic (space group Fm3̄m), ...
Magnetic properties of the half-metallic ferromagnet NiMnSb grown on InSb by pulsed laser deposition
(2004)
We have grown films of the half-metallic ferromagnet NiMnSb on single crystals of the narrow gap semiconductor InSb by pulsed laser deposition. NiMnSb is a possible candidate for spin injection applications. The film ...
Low temperature growth of In 2O 3 and InN nanocrystals on Si(111) via chemical vapour deposition based on the sublimation of NH 4Cl in In
(2009)
Indium oxide (In 2O 3) nanocrystals (NCs) have been obtained via atmospheric pressure, chemical vapour deposition (APCVD) on Si(111) via the direct oxidation of In with Ar:10% O 2 at 1000 °C but also at temperatures as low ...
On the linear stability of turbulent plane strain flow in a rotating frame
(2007)
We apply inviscid rapid distortion theory to the limiting hyperbolic case of turbulent plain strain flow in a rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the frame ...
