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 ...
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 ...
Growth of polycrystalline LaNi 1-xCo xO 3 (x = 0.3, 0.5) thin films on Si(100) by pulsed laser deposition
(2004)
Polycrystalline LaNi 1_xCo xO 3 (x = 0.5, 0.3) thin films have been deposited on polished Si(lOO) substrates by pulsed laser deposition. The films are grown at 650°C in ambient oxygen pressure of 0.4 mbar with an incident ...
