Novel ground states and spin ordering in iridate pyrochlores
We request four days of beam time to conduct zero and longitudinal field measurements on iridate pyrochlores A2Ir2O7 (A = Y, Lu, Nd) in the temperature range 200 K to 2 K and in... -
Anion disorder in Ti pyrochlores as a precursor in the transition to fluorite
The aim of this work is to understand the nature of anion disordering in pyrochlore oxides and to establish what, if any, correlations exist between the anion position, disorder... -
Determination of the crystal-electric field in geometrically frustrated pyroc...
Geometrically frustrated systems such as pyrochlore compounds receive much attention since they display exotic magnetic states. The explanation lies on the large degeneracy of... -
MuSR Study of Magnetically Frustrated Lu2Mo2(O,N)7 pyrochlores
The combination of magnetic frustration and low magnetic moment leads to non-classical magnetic behaviour such as spin liquid states. We have prepared polycrystalline samples of... -
High-resolution neutron diffraction studies of novel calcium niobate-based py...
This proposal is to determine high quality structural models using Rietveld analysis for the pyrochlore phases CaLnTr0.5Nb1.5O7 (Ln = La, Nd, Ho, Yb and Tr = Al, Sc, Cr, Mn, Fe,...
