Abstract

The properties of electron vortex beams are examined when subject to static magnetic fields. The fields are assumed to be applied after the electron vortex beam carrying a well-defined orbital angular momentum has been created as a result of using a holographicmask. The shifts in the electron vortex beam energy momentum as well as its angular momentum due to the presence of an axial uniform magnetic field are evaluated. Order-of-magnitude estimates of the shifts are given with reference to typical electron vortex beams subject to moderate magnetic fields.
