Quantum spin liquids are an exciting playground for exotic physical phenomena and
emergent many-body quantum states. The realization and discovery of quantum spin liquid …

Within the past 20 years or so, there has occurred an explosion of interest in the magnetic
behavior of pyrochlore oxides of the type A 2 3+ B 2 4+ O 7, where A is a rare-earth ion and …

Strong electron interactions can drive metallic systems toward a variety of well-known
symmetry-broken phases, but the instabilities of correlated metals with strong spin-orbit …

We review a key subset of the experimental studies that have recently focused on cubic
pyrochlore magnets whose pseudospin-1 2 degrees of freedom have mixed dipolar and …

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 …

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 …

In this Letter, we report a new spin ice—Pr 2 Sn 2 O 7—which appears to have enhanced
residual entropy due to the dynamic nature of the spins. Neutron scattering experiments …

The class of oxygen-ion-conducting rare-earth pyrochlores has been considerably
extended. New solid electrolytes, Ln 2 Ti 2 O 7 (Ln= Dy-Lu) and Ln 2 Hf 2 O 7 (Ln= Eu, Gd) …

Complex disordered states—from liquids and glasses to exotic quantum matter—are
ubiquitous in nature. Their key properties include finite entropy, power-law correlations and …

Electrical resistance is a crucial and well-understood property of systems ranging from
computer microchips to nerve impulse propagation in the human body. Here we study the …
