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 ...
Synthesis and physical properties of arc melted NiMnSb
(2004)
The synthesis and physical properties of arc melted NiMnSb were studied using X-ray diffraction analysis. It was observed that the half metallicity in NiMnSb is supported by the integer saturation magnetization value at 5 ...
Comparison of free surface polarization of NiMnSb and Co2 MnSi
(2006)
We present a systematic study of the polarization of the transport current from a variety of NiMnSb and Co2 MnSi thin films and bulk material using point contact Andreev reflection spectroscopy. The simple analysis suggests ...
