Abstract

We introduce a design of a neutron spin rotator for applications with space and temperature constraints. These passive devices employ remnant magnetization Fe- CoV thin films and can be tuned experimentally to achieve arbitrary rotation of an incident neutron with known spin state. Polarized neutron reflectometry measurements are reported for FeCoV monolayer films at thicknesses of 0.5 μm and 5.3 μm to characterize the depth-dependent vector magnetization in the films. Results for a prototype set of film rotators are presented and the stray field near such films is characterized.
