Frustrated Ferroelectricity in Niobate Pyrochlores
T. M. McQueen, B. Muegge, Q. Huang +3
The crystal structures of the A2B2O7-x Niobium-based pyrochlores Y2(Nb0.86Y0.14)2O6.91, CaYNb2O7, and Y2NbTiO7 are reported, determined by powder neutron diffraction. These compoun…
Magnetothermal study of Dy Stuffed Spin Ice: Dy2(DyxTi2-x)O7-x/2
B. G. Ueland, G. C. Lau, R. S. Freitas +6
We have studied the thermodynamics of the stuffed spin ice material, Dy2(DyxTi2-x)O7-x/2, in which additional Dy3+ replace Ti4+ in the pyrochlore Dy2Ti2O7. Heat capacity measuremen…
Stuffed Rare Earth Pyrochlore Solid Solutions
G. C. Lau, B. D. Muegge, T. M. McQueen +2
Synthesis and crystal structures are described for the compounds Ln2(Ti2-xLnx)O7-x/2, where Ln = Tb, Dy, Ho, Er, Tm, Yb, Lu, and x ranges from 0 to 0.67. Rietveld refinements on X-…
Zero Point Entropy in Stuffed Spin Ice
G. C. Lau, R. S. Freitas, B. G. Ueland +4
The third law of thermodynamics dictates that the entropy of a system in thermal equilibrium goes to zero as its temperature approaches absolute zero. In ice, however, a "zero poin…
