The Magnetic Scattering of Neutrons

Abstract
The interaction of neutrons with ferromagnetic materials has been investigated through a number of experiments. Because of the dependence of the interaction upon the spin orientation of the neutron relative to the magnetic field of the atom, and the effect of this spin dependent perturbation on the nuclear scattering, a beam of neutrons transmitted through or scattered from a magnetized iron plate becomes polarized by selective scattering.
