Abstract / Bemerkung
Magnetic tunnel junctions are prepared with Co-based Heusler compounds as one magnetic electrode and alumina as the tunnel barrier. The investigated compounds are Co2MnSi and Co2FeSi. An inversion of the tunnel magnetoresistance in the Co2FeSi as well as in the Co2MnSi case was found with alumina barriers at certain bias voltages at room and low temperatures. We present calculations of the density of states of these compounds based on fully relativistic spin-polarized KKR methods in order to elucidate the inversion. (C) 2008 American Institute of Physics.
