Magnetic order in the triangular quantum magnet AgNiO2
This proposal is part of our research programme on spin and orbital order in frustrated systems. AgNiO2 has a layered crystal structure with Jahn-Teller active Ni3+ ions forming... -
Magnetic Properties of Rare-Earth Carbonates
We have prepared a new family of rare-earth carbonates, R4(CO3)6(H2O)2en (R=Dy-Lu). With the exception of R=Er, all materials exhibit a steadily decreasing meff below 70K. The... -
Dynamical disorder or incipient nano-ferroic distortions in CaSnO3 perovskite?
It has always been assumed that CaSnO3 perovskite remains orthorhombic (Pbnm) as a function of temperature up to its melting point, and is rather unremarkable in many ways.... -
Cooperative Jahn-Teller distortions in Ru4+ double perovskites
The aim of the proposed experiment is to use HRPD to follow the temperature dependence of the crystal structures of the double perovskites La2MgRuO6 and La2CoRuO6. This is of... -
Structural distortions and magnetic ordering in oxygen depleted spin ice
Geometrical frustration in the spin ice material Dy2Ti2O7 leads to macroscopic degeneracy and the observation of magnetic diffuse neutron scattering down to the lowest... -
Enhanced oxygen hyperstoichiometry in Y doped La9.33+xGe6O26+3x/2
Apatite-type lanthanide silicates/germanates have been attracting considerable interest as a new class of oxide ion conductors. The presence of interstitial oxide ions is... -
Structural distortions and magnetism in the layered oxide sulfide Sr2MnO2Cu1.5S2
This proposal aims to exploit the superior flux on the upgraded HRPD coupled with the intrinsic high resolution to correlate the magnetic structure and the crystal structure of... -
The Influence of Post-Quench Delay on the Residual Stresses in Cold Compresse...
Residual stresses introduced into large aerospace aluminium components after the queching procedure carried out to form the desired microstructure can result in large, costly... -
