Polarized neutron channeling in weakly magnetic films
S. V. Kozhevnikov, V. D. Zhaketov, T. Keller +3
We describe a new sensitive method for the investigation of weakly magnetic films placed inside a tri-layer planar waveguide. Polarized neutrons tunnel into the waveguide through t…
Divergence of neutron microbeams from planar waveguides
S. V. Kozhevnikov, V. D. Zhaketov, T. Keller +3
Neutron planar waveguides are focusing devices generating a narrow neutron beam of submicron width. Such a neutron microbeam can be used for the investigation of local microstructu…
Neutron channeling in a nonmagnetic planar waveguide
S. V. Kozhevnikov, T. Keller, Yu. N. Khaydukov +2
We investigate neutron propagation in a middle layer of a planar waveguide which is a tri-layer thin film. A narrow divergent microbeam emitted from the end face of the film is reg…
Application of Zeeman spatial beam-splitting in polarized neutron reflectometry
S. V. Kozhevnikov, V. K. Ignatovich, F. Radu
Neutron Zeeman spatial beam-splitting is considered at reflection from magnetically noncollinear films. Two applications of Zeeman beam-splitting phenomenon in polarized neutron re…
Neutron resonances in planar waveguides
S. V. Kozhevnikov, V. K. Ignatovich, A. V. Petrenko +1
Results of experimental investigations of a neutron resonances width in planar waveguides using the time-of-flight reflectometer REMUR of the IBR-2 pulsed reactor are reported and…
Neutron Zeeman beam-splitting for the investigation of magnetic nanostructures
S. V. Kozhevnikov, F. Ott, E. Semenova
The Zeeman spatial splitting of a neutron beam takes place during a neutron spin-flip in magnetically non-collinear systems at grazing incidence geometry. We apply the neutron beam…
Polarized neutron channeling as a tool for the investigations of weakly magnetic thin films
S. V. Kozhevnikov, Yu. N. Khaydukov, T. Keller +2
We present and apply a new method to measure directly weak magnetization in thin films. The polarization of a neutron beam channeling through a thin film structure is measured afte…
Neutron methods for the direct determination of the magnetic induction in thick films
S. V. Kozhevnikov, F. Ott, F. Radu
We review different neutron methods which allow extracting directly the value of the magnetic induction in thick films: Larmor precession, Zeeman spatial beam-splitting and neutron…
Practical use of waveguides for polarized neutrons studies
S. V. Kozhevnikov, T. Keller, Yu. N. Khaydukov +6
We present the use of planar waveguides to produce neutron microbeams in order to investigate magnetic micro-structures with a micrometric spatial resolution. We report experimenta…
