ABSTRACT
The magnetization of a nanometer size Ni needle is observed using the coherent electron beam originating from an electron point source. This at one and the same time displays the local (Lorentz force) and the nonlocal (Aharonov–Bohm phase shift) magnetic effects. The experiments are performed at three orders of magnitude lower electron energy than previous nonlocal effects observations. These experiments open a way to quantitative magnetization measurements and to magnetic imaging at a nanometer scale.
