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 …

Frustration, the presence of competing interactions, is ubiquitous in the physical sciences
and is a source of degeneracy and disorder, which in turn gives rise to new and interesting …

Fractals—objects with noninteger dimensions—occur in manifold settings and length scales
in nature. In this work, we identify an emergent dynamical fractal in a disorder-free …

The discovery of the spin-ice phase in Dy2Ti2O7 numbers among the most significant
findings in magnetic materials in over a decade,,. Spin ice has since been associated with …

This contribution provides a thorough examination of the structural characteristics of
pyrochlore-type lanthanide titanates and zirconates Ln 2 Ti 2 O 7 and Ln 2 Zr 2 O 7, across …

The idea of magnetic monopoles in spin ice has enjoyed much success at intermediate
temperatures, but at low temperatures a description in terms of monopole dynamics alone is …

Frustrated systems, typically characterized by competing interactions that cannot all be
simultaneously satisfied, display rich behaviours not found elsewhere in nature. Artificial …

The pyrochlore spin ice compounds Dy 2 Ti 2 O 7 and Ho 2 Ti 2 O 7 are well described by
classical Ising models down to low temperatures. Given the empirical success of this …

In this work, we present inelastic neutron scattering experiments which probe the single ion
ground states of the rare-earth pyrochlores R 2 Ti 2 O 7 (R= Tb, Dy, Ho). Dy 2 Ti 2 O 7 and …

Low-temperature states of polycrystalline samples of a frustrated pyrochlore oxide Tb 2+ x Ti
2− x O 7+ y have been investigated by specific heat, magnetic susceptibility, and neutron …
