The pyrochlore lattice is associated with several potential and actual spin liquid phases as a result of its strong geometric frustration. At finite temperature, these can exhibit an unusually broad cross-over regime to a conventional paramagnet. Here, we study this regime analytically by showing how a single-tetrahedron Hamiltonian can extrapolate beyond the first term of a high-temperature expansion and yield insights into the build-up of correlations. We discuss how this unusual behaviour is…

Multiphase magnetism in Yb2Ti2O7

It is shown using neutron scattering on high-quality crystals that the unusual spectra may arise as a superposition of ferromagnetic and antiferromagnetic spin waves, which indicates that these disparate forms of magnetism actually coexist in Yb2Ti2O7, which is consistent with near-perfect degeneracy.

Insulating spin glasses

The possibility of obtaining spin glasses by addition of impurities in an antiferromagnetic insulator is examined. Dipolar interactions are briefly considered but the attention is focussed on

Order induced by dipolar interactions in a geometrically frustrated antiferromagnet

We study the classical Heisenberg model for spins on a pyrochlore lattice interacting via long-range dipole-dipole forces and nearest-neighbor exchange. Antiferromagnetic exchange alone is known not

Quantum spin configurations in Tb 2 Ti 2 O 7

Low-energy collective angular momentum states of the ${\mathrm{Tb}}^{3+}$ ions in ${\mathrm{Tb}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$ are classified according to the irreducible representations of

Rod motifs in neutron scattering in spin ice

Neutron scattering is a technique of choice to study magnetic correlations in real materials. Discerning topological contributions therein is, however, a tall order. Bow-tie features are a notable
