Tunneling anisotropic magnetoresistance in Fe/GaAs/Au junctions: orbital effects
M. Wimmer, M. Lobenhofer, J. Moser +6
We report experiments on epitaxially grown Fe/GaAs/Au tunnel junctions demonstrating that the tunneling anisotropic magnetoresistance (TAMR) effect can be controlled by a magnetic…
Investigations on unconventional aspects in the quantum Hall regime of narrow gate defined channels
J. Horas, A. Siddiki, J. Moser +2
We report on theoretical and experimental investigations of the integer quantized Hall effect in narrow channels at various mobilities. The Hall bars are defined electrostatically…
Bias dependent inversion of tunneling magnetoresistance in Fe/GaAs/Fe tunnel junctions
J. Moser, M. Zenger, C. Gerl +10
We investigated spin dependent transport through Fe/GaAs/Fe tunnel junctions. The tunneling magnetoresistance effect (TMR) was probed for different types of Fe/GaAs interfaces. For…
High-field magnetoresistance of Fe/GaAs/Fe tunnel junctions
M. Zenger, J. Moser, W. Wegscheider +2
We investigate transport through 6 to 10 nm thin epitaxial GaAs(001) barriers sandwiched between polycrystalline iron films. Apart from a pronounced tunneling magnetoresistance eff…
