Recent very detailed neutron powder-diffraction studies performed by Lawson et al. (1986) revealed very complex magnetic structures below 30 K which are schematically drawn in fig. 3.5. The ferromagnetic structure below 30 K consists of alternating layers of magnetic (with a moment of l)iB) denoted by 1 and non-magnetic uranium atoms denoted by 0 on which there is superimposed a non-colhnear antiferromagnetic structure which itself re-orders at 20 K (near the temperature of the second transition indicated by the bulk measurements). The ferromagnetic...

Diffraction studies have been used in a small number of cases to determine the minimum energy positions of adsorbed moleeules within cationic zeolites. These difficult and relatively expensive experiments have been used to establish computational simulation as a reliable method to predict such interactions without recourse to experimentation. Crystallographic X-ray studies of the adsorption of small moleeules sueh as CO and NO on cationic forms of zeolite are of particular relevance to study of eation-molecule interactions, as are neutron powder diffraction studies of the location of pyridine, coordinatively bound to potassium ions in zeolite K-L, and of benzene, bound to sodium ions in zeolite Na-X. ... 

For the network of stoichiometry [Mn Fe (ox)3], one encounters the rare situation of a bimetallic lattice in which both metal ions have the same electronic ground state, namely 3i/ , S = 5/2, T i. In this case, the compound has been found to mimic antiferromagnetic behavior. Thus the temperature dependence of the magnetic susceptibility is that of a classic two-dimensional antiferro-magnet, reaching a broad maximum at 55 K. Definitive evidence for this behavior comes from a neutron powder diffraction study, which revealed a simple collinear antiferromagnetic alignment of Mn and Fe moments parallel to the c-axis, or in other words perpendicular to the layers.
