LiHoF: Cuboidal Demagnetizing Factor in an Ising Ferromagnet
Mikael Twengström, Laura Bovo, Oleg A. Petrenko +2
The demagnetizing factor has an important effect on the physics of ferromagnets. For cuboidal samples it depends on susceptibility and the historic problem of determining this func…
Pauling entropy, metastability and equilibrium in DyTiO spin ice
S. R. Giblin, M. Twengström, L. Bovo +17
Determining the fate of the Pauling entropy in the classical spin ice material DyTiO with respect to the third law of thermodynamics has become an important test case f…
Emergent Electrochemistry in Spin Ice: Debye-Hückel Theory and Beyond
Vojtěch Kaiser, Jonathan Bloxsom, Laura Bovo +3
The low-temperature picture of dipolar spin ice in terms of the Coulomb fluid of its fractionalised magnetic monopole excitations has allowed analytic and conceptual progress far b…
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…
Determination of the Entropy via Measurement of the Magnetization: Application to the Spin ice Dy2Ti2O7
L. Bovo, S. T. Bramwell
The residual entropy of spin ice and other frustrated magnets is a property of considerable interest, yet the usual way of determining it, by integrating the heat capacity, is gene…
Crystal Shape-Dependent Magnetic Susceptibility and Curie Law Crossover in the Spin Ices Dy2Ti2O7 and Ho2Ti2O7
L. Bovo, L. D. C. Jaubert, P. C. W. Holdsworth +1
We present an experimental determination of the isothermal magnetic susceptibility of the spin ice materials Dy2Ti2O7 and Ho2Ti2O7 in the temperature range 1.8-300 K. The use of sp…
Magnetoelastic excitations in the pyrochlore spin liquid TbTiO
T. Fennell, M. Kenzelmann, B. Roessli +9
At low temperatures, TbTiO enters a spin liquid state, despite expectations of magnetic order and/or a structural distortion. Using neutron scattering, we have discover…
