Quenched crystal field disorder and magnetic liquid ground states in Tb2Sn2-xTixO7
B. D. Gaulin, E. Kermarrec, M. L. Dahlberg +11
Solid-solutions of the "soft" quantum spin ice pyrochlore magnets Tb2B2O7 with B=Ti and Sn display a novel magnetic ground state in the presence of strong B-site disorder, characte…
Low temperature dynamic freezing and the fragility of ordering in Tb2Sn2O7
M. L. Dahlberg, M. J. Matthews, P. Jiramongkolchai +2
We have probed the low temperature magnetic behavior of the ordered spin ice material Tb2Sn2O7 through ac magnetic susceptibility measurements of both the pure material and samples…
Coexisting Magnetic Order and Cooperative Paramagnetism in the Stuffed Pyrochlore Tb_{2+x}Ti_{2-2x}Nb_xO_7
B. G. Ueland, J. S. Gardner, A. J. Williams +6
Neutron scattering and magnetization measurements have been performed on the stuffed pyrochlore system Tb2+xTi2-2xNbxO7. We find that despite the introduction of chemical disorder…
Zero-point entropy of the spinel spin glasses CuGa_2O_4 and CuAl_2O_4
L A Fenner, A S Wills, S T Bramwell +2
The zero-point entropy of a spin glass is a difficult property to experimentally determine and interpret. Spin glass theory provides various predictions, including unphysical ones,…
Magnetothermodynamics of the Ising Antiferromagnet Dy2Ge2O7
X. Ke, M. L. Dahlberg, E. Morosan +3
We report systematic low temperature measurements of the DC magnetization, AC susceptibility, and heat capacity of dysprosium pyrogermanate (Dy2Ge2O7) single crystal and powder sam…
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…
