Abstract

We propose an itinerant electron theory of nonmonotonic inelastic tunneling spectra of ferromagnetic junctions observed in several recent experiments. Assuming that the Coulomb interaction between electrons across the barrier is poorely screened due to the exponential suppression of the band electron density inside the barrier, we consider a process where a hot electron from one ...
