  • Abstract
    This study aims to investigate the relationship between localized states and spin-dependent transport properties by means of dependence of the differential conductance and inelastic electron tunnelling signals on the measurement frequency. It is shown that the differential conductance decreases with increase in the measurement frequency. The results indicate that the extrinsic spin dependent signals, originates from localized states/interface traps, can be separated by measuring dependence of differential conductance on the measurement frequency.
