Structure determination of perovskites, high temperature superconductors and zeolites on the KSN-2 powder neutron diffractometer

摘要

The research activities at the Laboratory of Neutron Diffraction (Faculty of Nuclear Sciences and Physical Engineering (CTU Prague) are focused on neutron scattering for solid state physics and materials science investigations. We have investigated a some promising materials, e.g. perovskites (Pr_(1-x)K_xMnO_3, Pr_(1-x)Na_xMnO_3 and Pr_(1-x)Ca_xMnO_3), high temperature superconductors (types Bi-Sr-Ca-Cu-O, Y-Ca-Ba-Cu-O) and zeolites (types Na-Y, Na-(H, D)Y, Na-X, Na-(H, D)X). Results obtained on the KSN-2 diffractometer by powder neutron diffraction method during last years are given.
