Thermal conductivity of Ni, Co, and Fe-doped La5Ca 9Cu24O41 thin films measured by the 3ω method
(2010)
The effect of Ni-, Co- and Fe-substitution for Cu on the thermal conductivity of La5Ca9Cu24O41 thin films is investigated. Highly b-axis oriented polycrystalline films were grown onto MgO (100) substrates using the pulsed ...
Hall effect study of magnetoresistive perovskite LaNi0.5Co 0.5O3 thin films
(2004)
We report on the Hall effect of LaNi0.5Co0.5O 3 magnetoresistive thin films grown on Si(100) substrates by pulsed laser deposition. The Hall resistivity exhibits sign reversals both in varying magnetic field and temperature, ...
Minority-spin band parameters in a NiMnSb thin film determined by spectral conductivity
(2004)
NiMnSb is expected to be a ferromagnetic half metal, an expectation that is based in part on band structure calculations. Here we report optical conductivity studies of the band structure for a film prepared by pulsed laser ...
Ambiguous Role of Growth-Induced Defects on the Semiconductor-to-Metal Characteristics in Epitaxial VO2/TiO2 Thin Films
(2018)
Controlling the semiconductor-to-metal transition temperature in epitaxial VO2 thin films remains an unresolved question both at the fundamental as well as the application level. Within the scope of this work, the effects ...
Growth and structural characterization of orthorhombic and tetragonal SrCuO2 thin films
(2013)
Epitaxial SrCuO2 thin films were grown on (0 0 1) SrTiO 3 substrates by pulsed laser deposition using a stoichiometric target. X-ray diffraction indicated that the SrCuO2 films undergo a structural phase transition as a ...
Pulsed laser deposition and thermal characterization of Ni-doped La5Ca9Cu24O41 thin films
(2011)
Highly b-axis oriented polycrystalline Ni-doped La5Ca 9Cu24O41 thin films have been grown on (0 0 1) SrTiO3 substrates using the pulsed laser deposition technique. EDX measurements have revealed nearly stoichiometric ...
Large positive magnetoresistance in nonstoichiometric NiMnSb thin films on silicon
(2004)
The transport properties of pulsed-laser-deposited NiMnSb films on silicon as a function of film thickness were discussed. It was found that a low-temperature upturn was observed in the resistivity for film thicknesses of ...
Spin polarisation and anomalous Hall effect in NiMnSb films
(2004)
NiMnSb has attracted a great deal of interest as a spin injector/detector in spintronic devices because it has a Curie temperature of 728 K and is predicted to be half-metallic (100% spin polarized). NiMnSb has been reported ...
Magneto-transport properties of NiMnSb thin films on InSb single crystals: Negative giant magnetoresistance
(2007)
In this study we investigated the magneto-transport properties of the ohmic contact between polycrystal-line NiMnSb thin films grown by pulsed laser deposition and n-type degenerate InSb (100) substrates. An unusual negative ...
Structural, magnetic, and electrical properties of NiMnSb thin films grown on InSb by pulsed-laser deposition
(2004)
We report the growth of single-phase, stoichiometric polycrystalline thin films of the half-Heusler ferromagnet NiMnSb, predicted to be half-metallic, on single crystal InSb (100) substrates heated at 200°C by pulsed laser ...
