Abstract

It is in principle possible to recover phase information regarding an unknown, non-magnetic film structure in reflectivity measurements with polarized neutrons if the film is deposited on a substrate with a buried ferromagnetic layer of known thickness. One particular method is described here for inverting plus and minus neutron reflectivity data in the kinematic limit to obtain the chemical density profile of an 'unknown' layer. Application of this method in the dynamical regime is not as straightforward, and will be discussed. Nonetheless, experimental results demonstrate the value of simultaneously fitting plus and minus reflectivity data in the dynamical case in limiting the number of possible ambiguous results.
