Quantum spin liquids may be considered'quantum disordered'ground states of spin systems,
in which zero-point fluctuations are so strong that they prevent conventional magnetic long …

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 …

In frustrated quantum magnets, long-range magnetic order fails to develop despite a large
exchange coupling between the spins. In contrast to the magnons in conventional magnets …

The Tb 2 Ti 2 O 7 pyrochlore magnetic material is attracting much attention for its spin liquid
state, failing to develop long-range order down to 50 mK despite a Curie-Weiss temperature …

Inelastic neutron scattering reveals a broad continuum of excitations in Pr 2 Zr 2 O 7, the
temperature and magnetic field dependence of which indicate a continuous distribution of …

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 …

Quantum spin liquid (QSL) is a disordered state of quantum-mechanically entangled spins
commonly arising from frustrated magnetic dipolar interactions. However, QSL in some …

At low temperatures, Tb 2 Ti 2 O 7 enters a spin liquid state, despite expectations of
magnetic order and/or a structural distortion. Using neutron scattering, we have discovered …

Neutron scattering measurements show the ferromagnetic XY pyrochlore Yb 2 Ti 2 O 7 to
display strong quasi-two-dimensional (2D) spin correlations at low temperature, which give …

Pyrochlore iridates and pyrochlore ices are two families of materials where novel quantum
phenomena are intertwined with strong spin-orbit coupling, substantial electron correlation …
