We report a new method that uses magnetic birefringence to enhance the contrast in a neutron interferometer. We performed model calculations for interference-fringe contrast in a Mach–Zehnder-type neutron interferometer with an improperly aligned multilayer mirror and inhomogeneous magnetic fields. Our calculations showed that, by using inhomogeneous magnetic fields, we could recover the decreased contrast caused by the improper alignment of the mirrors.
