On the Application of Zeeman Spatial Beam Splitting in Polarized Neutron Reflectometry

Abstract

Zeeman spatial neutron beam splitting is considered upon reflection from a homogeneous magnetic film placed in an external magnetic field applied at an angle to the surface of a sample. Two ways of applying the Zeeman beam-splitting phenomenon in polarized neutron reflectometry are discussed. One of them is the construction of polarizing devices with a high polarization efficiency. The other is investigations of magnetically noncollinear films at a low spin-flip probability of reflected neutrons. The experimental results are presented for illustration.
