The spin ice materials, including Ho 2 Ti 2 O 7 and Dy 2 Ti 2 O 7, are rare-earth pyrochlore
magnets which, at low temperatures, enter a constrained paramagnetic state with an …

Extensive experimental investigations of the magnetic structures and excitations in the XY
pyrochlores have been carried out over the past decade. Three families of XY pyrochlores …

The “spin-ice” state found in the rare-earth pyrochlore magnets Ho 2 Ti 2 O 7 and Dy 2 Ti 2 O
7 offers a beautiful realization of classical magnetostatics, complete with magnetic monopole …

The Coulomb phase, with its dipolar correlations and pinch-point–scattering patterns, is
central to discussions of geometrically frustrated systems, from water ice to binary and mixed …

The family of magnetic rare-earth pyrochlore oxides R 2 M 2 O 7 plays host to a diverse
array of exotic phenomena, driven by the interplay between geometrical frustration and spin …

In a class of frustrated magnets known as spin ice, magnetic monopoles emerge as classical
defects and interact via the magnetic Coulomb law. With quantum-mechanical interactions …

A series of Yb 2+ x Ti 2− x O 7− δ doped samples demonstrates the effects of off-
stoichiometry on Yb 2 Ti 2 O 7's structure, properties, and magnetic ground state via x-ray …

Recent neutron scattering and specific heat studies on the pyrochlore Yb 2 Ti 2 O 7 have
revealed variations in its magnetic behavior below 265 mK. In the best samples, a sharp …

We use numerical linked-cluster expansions to compute the specific heat C (T) and entropy
S (T) of a quantum spin ice Hamiltonian for Yb 2 Ti 2 O 7 using anisotropic exchange …

We use neutron scattering to show that ferromagnetism and antiferromagnetism coexist in
the low T state of the pyrochlore quantum magnet Yb 2 Ti 2 O 7. While magnetic Bragg …
