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, ...
Thickness dependence of Hall transport in Ni1.15Mn 0.85Sb thin films on silicon
(2004)
Highly spin polarized Heusler alloys, NiMnSb and Co2MnSi, attract a great deal of interest as potential spin injectors for spintronic applications. Spintronic devices require control of interfacial properties at the ...
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 ...
Recent advances in spintronics. Half-metal ferromagnets: Their role in spintronics
(2004)
A review of recent advances in spintronics is presented. We report the structural, magnetic, electrical and thermal properties of the ferromagnetic half-Heusler alloy NiMnSb grown by arcmelting. The bulk material is used ...
Negative giant longitudinal magnetoresistance in NiMnSb InSb: Interface effect
(2006)
We report on the electrical and magnetotransport properties of the contact formed between n -type degenerate InSb (100) substrates and polycrystalline NiMnSb thin films grown using pulsed laser deposition. Negative giant ...
Possible use of the half-Hausler alloy NiMnSb in spintronics: Synthesis and physical properties of arc melted NiMnSb and of NiMnSb thin films grown on InSb by pulsed laser deposition
(2005)
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 (100) InSb substrates heated at 200 °C by pulsed laser ...
Indium oxide as a possible tunnel barrier in spintronic devices
(2005)
We report the growth of ultra-thin indium oxide layers using the dc-magnetron sputtering method. We demonstrate that good quality tunnel barriers made of indium oxide can be routinely fabricated and employed in spintronic-related ...
Ferromagnetic and antiferromagnetic interactions in lanthanum cobalt oxide at low temperatures
(2001)
Systematic dc and ac magnetic susceptibility studies have been performed on single-phase (formula presented) powder samples. Evidence is presented in support of the existence of ferromagnetic (FM1, FM2) and antiferromagnetic ...
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 ...
