- Descrição
- We evaluate the amplitude of the Larmor frequency component of the scanning tunneling microscope current induced by a single resonating spin, in a model in which the tunneling barrier is modulated via spin-orbit interaction. From Kramer's theorem follows however, that the barrier height modulation cannot have Larmor components and such components in the current are caused by its non-linear dependence with the barrier height. We obtain an effect which is five orders of magnitude smaller than that reported by Y.Manassen et. al.[Phys.Rev.Lett.,62, 2531,1989].
