Dynamical Scattering of Polarized Neutrons by Thin Magnetic Films
Published online by Cambridge University Press: 03 September 2012
Abstract
Using Larmor precession as a clock, Buttiker1 identified theoretical times for the scattering of particles from an opaque slab coincident with a magnetic field. The subsequent model generated interesting predictions for the influence of opaque regions on the magnetic polarization of the transmitted and reflected beams. Previous attempts to verify these predictions were unable to do so unambiguously2. Here, Biittiker's formulae are extended to more general geometries. An experiment has been devised to test the theory by measuring neutron beam polarization in both reflection from and transmission through magnetic films below the critical angle for external reflection.
