Query: Application of Zeeman spatial beam-splitting in polarized neutron
  reflectometry   Neutron Zeeman spatial beam-splitting is considered at reflection from
magnetically noncollinear films. Two applications of Zeeman beam-splitting
phenomenon in polarized neutron reflectometry are discussed. One is the
construction of polarizing devices with high polarizing efficiency. Another one
is the investigations of magnetically noncollinear films with low spin-flip
probability. Experimental results are presented for illustration.
