      abstract     = {In 1949, at the end of a paper dedicated to the concept of
                      the refractive index in electron optics, Ehrenberg and Siday
                      noted that wave-optical effects will arise from an isolated
                      magnetic field even when the rays themselves travel in
                      magnetic-field-free space. They proposed a two-slit
                      experiment, in which a magnetic flux is enclosed between
                      interfering electron beams. Now, through access to modern
                      nanotechnology tools, we used a focused ion beam to open two
                      nanosized slits in a gold-coated silicon nitride membrane
                      and focused electron beam induced deposition to fabricate a
                      thin magnetic bar between the two slits. We then performed
                      Fraunhofer experiments in a transmission electron microscope
                      equipped with a field emission gun and a Lorentz lens. By
                      tilting the specimen in the objective lens field of the
                      electron microscope, the magnetization of the bar could be
                      reversed and the corresponding change in the phase of the
                      electron wave observed directly in the form of a shift in
                      the interference fringe pattern.},
