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...
متن کاملA neutron diffraction study on the location of the polyene chain of retinal in bacteriorhodopsin.
We report on the location of the chain part of the retinylidene chromophore in the projected density of bacteriorhodopsin as determined by neutron diffraction from the two-dimensional purple membrane lattice. For this purpose, partially deuterated retinal was synthesized containing 10 deuterons at positions C-8, C-10, C-12, C-14, C-19(3), and C-20(3) of the polyene chain. Two sets of dark-adapt...
متن کاملNeutron Diffraction and Mössbauer Studies of Zinc Ferrite
It is shown by neutron diffraction and Mossbauer spectrometry that the formation of a long range magnetic order in zinc ferrite depends sensitivily on the content of divalent iron. The experimental data favour a non collinear model of the magnetic structure. Zinc ferrite is a normal spinel with the tetrahedral A sites occupied by Zn2+ ions and the octahedral B sites occupied by Fe3+ ions. Any m...
متن کاملNeutron diffraction studies of water and aqueous solutions under pressure
2014 A summary is given of data obtained from neutron diffraction experiments on heavy water at elevated pressures and temperatures using three different types of pressure vessel. The pressure vessels were manufactured from (i) hard steel (EN24T), (ii) titanium-zirconium null alloy, and (iii) autofrettaged aluminium alloy (7075-T6). In cases (i) and (ii), hydraulic pressures up to 6 kbar were a...
متن کاملOxides: neutron and synchrotron X-ray diffraction studies
We shall review some results from several areas of oxide science in which neutron scattering and X-ray synchrotron scattering exercise a complementary role to high-resolution transmission electron microscopy. The very highresolution time-of-flight neutron diffraction technique and its role in studies of the magnetic structure of oxides will especially be reviewed. The selected topics of structu...
