reflectivities for up and down polarised neutrons at high fields confirms a finite magnetisation of the multilayer, which is expressed in a finite magnetic SLD (middle left panel). At remanence the splitting ... assumed to have a domain- like structure as shown in the sketch (bottom right pane). At the applied field of 5 kOe, the NPs’ magnetic ...

arrangement of polymer micelles with a diameter of about 180 Å close to a hydrophilic and a hydrophobic coated silicon wafer. For the top panels the sample is in a liquid phase. The ring of increased intensity ... sample in a crystalline cubic phase. Close to the hydrophilic interface a cubic close packed structure is formed whereas close to the ...

separation of ethanol from water using a vapor permeation method. Using isotope contrast, neutron reflectivity was applied to evaluate the amounts of solvents intercalated into a membrane from pure and binary vapors ... The interlayer spacing of GO and the amount of intercalated solvents were evaluated simultaneously as a function of vapour ...

so-called MAX phases is a topic of some controversy. Here we present unpolarized neutron-diffraction data between 3.4 and 290.0 K and momentum transfer between Q = 0.0 and 1.1 A-1 on epitaxial thin films ... material exhibits neutron-diffraction peaks consistent with long-ranged antiferromagnetic order with a periodicity of two structural unit ...

reflectivity from a 56Fe/57Fe superlattice clearly shows the layering of the sample with sharp interfaces. The inset reproduces the film thickness oscillations from the superlattice with a total thickness
