Structure and magnetic properties from neutron data below 10 K

Magnetic structure of MnO at 10 K from total neutron scattering data.

Total neutron scattering data from a powdered sample of MnO collected at 10 K have been analyzed using the reverse Monte Carlo method to refine the nuclear and magnetic structure. The results give the first unambiguous assignment of the average magnetic structure. The magnetic moments are aligned ferromagnetically within (111) sheets with the magnetization vectors of alternate sheets along axes...

Neutron Structure Functions From Nuclear Data

The spin-averaged structure function of the neutron, F n 2 , is extracted from recent deuteron data, taking into account the small but significant corrections from nuclear effects in the deuteron. At small x, the F D 2 /F p 2 ratio measured by the New Muon and Fermilab E665 Collaborations is interpreted to suggest a small amount of shadowing in deuterium, which acts to enhance F n 2 for x < ∼ 0...

The structure of phosphate glass biomaterials from neutron diffraction and 31P nuclear magnetic resonance data.

Neutron diffraction and 31P nuclear magnetic resonance spectroscopy were used to probe the structure of phosphate glass biomaterials of general composition (CaO)0.5-x(Na2O)x(P2O5)0.5 (x = 0, 0.1 and 0.5). The results suggest that all three glasses have structures based on chains of Q2 phosphate groups. Clear structural differences are observed between the glasses containing Na2O and CaO. The P-...

Recent magnetic structure studies by neutron diffraction

2014 A review is presented of several magnetic structure studies performed recently by neutron diffraction methods. These include a study of the low temperature transition in Fe3O4 by Hamilton and experiments by Roth on the magnetic structure ambiguities of the transition element monoxides. Recent studies using polarized neutron beam techniques are described and data presented on the ferromagne...
