We demonstrate two different applications of the spatial spin-resonance (SS
R) technique for monochromatization and shaping of the spectrum of a polari
zed neutron beam. Firstly, SSR monochromator with the adjusting gradient of
the guide magnetic field and secondly, SSR-monochromator with modulated sp
atial periodicity of static periodic magnetic field. (C) 2000 Elsevier Scie
