Comparative study of the magnetic and magnetotransport properties of a metallic and a semiconducting member of the solid solution LaNixCo1-xO3
(2003)A metallic and a semiconducting member of the solid solution LaNixCo1-xO3 (x=0.2, 0.6) with their magnetic and magnetotransport properties was investigated. The members of the perovskite solid solution were found on opposite ...

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, ...

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 ...

Investigation of spin-polarized resonant tunneling through double-barrier magnetic tunnel junctions by self-consistent solution of the Poisson-Schrödinger equations
(2003)The article discusses the investigation of spin-polarized resonant tunneling through double barrier magnetic tunnel junctions (DBMTJ) by the self-consistent solution of Poissons and Schrödingers equations using transfer ...

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 ...

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 ...

Magnetoresistance in LaNi1-xCoxO3 (0.3≤x≤0.6)
(2010)We report on a detailed study of the electrical resistivity and the magnetoresistance of the metallic members of the LaNi1-xCoxO3 series with 0.3≤x≤0.6. The low-temperature resistivity of the compounds with 0.3≤x≤0.5 ...

Magnetoresistance of magnetite thin films grown by pulsed laser deposition on GaAs(1 0 0) and Al2O3(0 0 0 1)
(2007)Magnetotransport properties of magnetite thin films deposited on gallium arsenide and sapphire substrates at growth temperatures between 473 and 673 K are presented. The films were grown by UV pulsed laser ablation in ...
