Neutron Diffraction under Grazing Incidence: Recent Results from the Evanescent Wave Diffractometer
We report the first exit angle resolved magnetic neutron diffraction experiment under grazing incidence. The antiferromagnetic (100) Bragg reflection was excited under grazing incidence on a (001) MnF2 single crystal surface. By a careful control of the exit angle we were able to identify unambiguously the surface scattering. We present the experimental set up and compare some results with those of a CaF2 single crystal.
