Abstract
We report the observation of enhanced spin-dependent shot noise in magnetic tunnel barriers, suggesting transport through localized states within the barrier. This is supported by the existence of negative magnetoresistance and structure in the differential conductance curves. A simple model of tunneling through two interacting localized states with spin-dependent tunneling rates is used to explain our observations.
