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, ...
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 ...
Disorder-induced vortex phase transition in untwinned YBa2Cu3O7-δ crystal
(2000)
Local magnetic measurements in an untwinned YBa2Cu3O7-δ crystal as a function of temperature, field and time reveal anomalies occurring along the same line BSS(T) in the field-temperature plane. We identify BSS(T) as a ...
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 ...
Coexistence of ferromagnetic and glassy behavior in semiconducting LaNi 0.2Co 0.8O 3
(2002)
Systematic dc and ac magnetic susceptibility studies have been performed on single-phase LaNi 0.2Co 0.8O 3 powder samples. Evidence of hysteresis loops supports the existence of ferromagnetic correlations that lead to a ...
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 ...
Thermoelectric properties of LaNi1-xCoxO3 solid solution
(2003)
The thermoelectric properties of the selected members of the LaNi 1-xCoxO3 solid solution were investigated. The electrical properties of the solution investigated were determined from the doping level. The substitution ...
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 ...
