Quenched salt hydrates new ways of probing water clusters.
Very rapid quenching of liquids to form a glass, from which crystalline phases are subsequently obtained by devitrification, is a powerful technique for obtaining novel... -
Interaction between slow dynamics of nuclear and magnetic domains in relaxor ...
Neutron experiment is carried out on relaxor magnet LuFeCoO4 to study the coupling between the slow dynamics of the dielectric and magnetic properties. At 190 K, the nuclear and... -
Understanding of Competing Magnetic Processes in La0.7Sr0.3MnxFe1-xO3 Perovskite
Perovskite manganates with the general formula L1-xAxMnO3 (e.g. L=La, Pr , Nd and A=Ca and Sr) have attracted significant interest as a result of their unusual transport and... -
Magnetic excitations in square lattice 2D Heisenberg Antiferromagnet Sr3Fe2O6.5
Strontium iron oxides belonging to the RP series Srn+1FenO3n+1 (n = 1, 2, ..,1) may offer unique insights into the differences between the magnetic properties of the... -
High-pressure neutron diffraction studies of valence transitions in ACu3Fe4O12
Two new A-site ordered perovskite structure oxides, CaCu3Fe4O12 and LaCu3Fe4O12, were recently synthesized under high-pressure and high-temperature conditions in Kyoto. These... -
Structural phase diagram of rare earth substituted multiferroic BiFeO3
BiFeO3 is one of the most widely studied multiferroics (ferroelectric TC ~ 830°C, and antiferromagnetic TN ~ 370°C). Rare earth doping has been shown to be a suitable method of... -
From giant magneto-elastic coupling to negative thermal expansion
We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a... -
Strain analysis of commensurate charge order/zener polaron ordering transitio...
High resolution powder diffraction data will be used to obtain lattice parameter and atomic coordinate variations as a function of temperature for Pr0.6Ca0.4MnO3, which has a... -
Variable Temperature Study of thallium and caesium azides
This proposal seeks to investigate the effect of temperature on the structures of thallium and caesium azide. High-resolution neutron powder diffraction data are necessary to...
