TL;DR: In this article, the total reflection of electromagnetic waves from an inhomogeneous region is considered and the phase shift on reflection is π/2 + Φ radians, where Φ is a correction given graphically in the letter.
Abstract: Total reflection of electromagnetic waves from an inhomogeneous region is considered. The transition region has a linearly varying relative permittivity. The phase shift on reflection is π/2 + Φ radians, where Φ is a correction given graphically in the letter.

TL;DR: In this article, the total external reflection of monochromatic neutrons has been measured on cobalt and iron thin films evaporated on glass substrates with a magnetic field applied parallel to the plane of the film.
Abstract: The total external reflection of monochromatic neutrons has been measured on cobalt and iron thin films evaporated on glass substrates. Neutron scattering from the thin‐film neutron mirrors was studied with a magnetic field applied parallel to the plane of the film. The changes in the cobalt mirror reflectivity curves with field strength can be correlated with local spin direction variations brought about by perpendicular anisotropy. By contrast, iron films show no field dependence which is consistent with measured planar coercive fields and the absence of a strong perpendicular anisotropy.
