Abstract The evolution of investigations with polarized neutrons using pulsed neutron sources with short and long pulses in Dubna is discussed. Some peculiarities of the use of long-pulse neutron sources are investigated. Author Keywords: Polarized neutrons; Pulsed neutron sources; Magnetism; Surfaces; Multilayers Article Outline 1. Introduction 2. Polarized neutrons investigations in Dubna 3. Instrumentation with polarized neutrons at IBR-2 4. Reflectometry at IBR-2 5. Conclusion References Enlarge Image (8K) Fig. 1.

(a) Intensity map of specular and off-specular scattered neutrons (spin-down) from the Fe/Cr multilayer at H=0.428 kG as a function of small lambda, Greek and small alpha, Greek final, the neutron wavelength and outgoing scattering angles, respectively; incident angle small alpha, Greeki=15 mrad. The strong intensity along the horizontal line at small alpha, Greeki=15 mrad corresponds to the specular reflection. Off-specular scattering in the form of 1/2 and 3/2 order Bragg sheets crosses the specular line around 4.5 and 1Å, respectively, and is determined by the domain structure of the multilayer. Yoneda scattering appears at the specular line at the critical wavelength small lambda, Greek=12.5 Å and interferes with the Bragg sheet scattering for smaller wavelengths. Off-specular scattering through the total thickness oscillations arises to conformal interfacial roughness; (b) result of the supermatrix calculation with the model of noncollinear domains [21 <#bib21>].
