      Magnetic properties of Fe/AlO x/GaAs(001) structures 

      Vaz, C. A. F.; Ionescu, A.; Trypiniotis, Theodossis; Bland, J. A. C.; Dalgliesh, R. M.; Langridge, S. (2005)
      We report results on the effect of the Al Ox barrier layer on the magnetic moment of Fe using polarized neutron reflection. The sample has nominal composition 25 nm Au5 nm Fe1.3 nm Al Ox GaAs (001). The metal deposition ...

      Magneto-transport properties of NiMnSb thin films on InSb single crystals: Negative giant magnetoresistance 

      Gardelis, S.; Androulakis, J.; Viskadourakis, Z.; Papadopoulou, E. L.; Giapintzakis, John; Rai, S.; Lodha, G. S.; Roy, S. B. (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 ...
