Building an atomic-scale vacuum trap for spin-polarized electrons
We experimentally realized a spin-resolved electron interferometer on the atomic scale by placing an atomically sharp magnetic probe tip in front of a magnetic sample surface and realizing a one-dimensional trap for electrons in the gap.
