Pauling entropy, metastability and equilibrium in Dy $_{2}$ Ti $_{2}$ O $_{7}$ spin ice

S. R. Giblin, M. Twengström, L. Bovo +17

Determining the fate of the Pauling entropy in the classical spin ice material Dy $_{2}$ Ti $_{2}$ O $_{7}$ with respect to the third law of thermodynamics has become an important test case f…

Phonon-mediated spin-flipping mechanism in the spin ices Dy $_{2}$ Ti $_{2}$ O $_{7}$ and Ho $_{2}$ Ti $_{2}$ O $_{7}$

M Ruminy, S Chi, S Calder +1

To understand emergent magnetic monopole dynamics in the spin ices Ho $_{2}$ Ti $_{2}$ O $_{7}$ and Dy $_{2}$ Ti $_{2}$ O $_{7}$ , it is necessary to investigate the mechanisms by which spins flip in the…

Neutron Larmor diffraction investigation of the rare earth pyrochlores $R_{2}$ Ti $_{2}$ O $_{7}$ ( $R$ = Tb, Dy, Ho)

M Ruminy, F Groitl, T Keller +1

In this work we present a neutron Larmor diffraction study of the rare earth pyrochlores $R_{2}$ Ti $_{2}$ O $_{7}$ , with $R$ = Tb, Dy, Ho. We measured the temperature dependence of the latt…

First principles calculation and experimental investigation of lattice dynamics in the rare earth pyrochlores R2Ti2O7 (R=Tb, Dy, Ho)

M Ruminy, M Nunez Valdez, B Wehinger +15

We present a model of the lattice dynamics of the rare earth titanate pyrochlores R2Ti2O7 (R=Tb, Dy, Ho), which are important materials in the study of frustrated magnetism. The ph…

Sample independence of magnetoelastic excitations in the rare earth pyrochlore Tb2Ti2O7

M. Ruminy, L. Bovo, E. Pomjakushina +6

Recent experimental results have emphasized two aspects of Tb2Ti2O7 which have not been taken into account in previous attempts to construct theories of Tb2Ti2O7: the role of small…

Magnetoelastic excitations in the pyrochlore spin liquid Tb $_{2}$ Ti $_{2}$ O $_{7}$

T. Fennell, M. Kenzelmann, B. Roessli +9

At low temperatures, Tb $_{2}$ Ti $_{2}$ O $_{7}$ enters a spin liquid state, despite expectations of magnetic order and/or a structural distortion. Using neutron scattering, we have discover…
