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 …

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 …

In this review, we provide an introduction to the physics of a series of frustrated quantum rare-
earth pyrochlores. We first give a background on the microscopic single-and two-ion physics …

We suggest that a randomization of the pseudodipolar interaction in the spin-orbit-generated
low-energy Hamiltonian of YbMgGaO 4 due to an inhomogeneous charge environment from …

Frustrated quantum magnets not only provide exotic ground states and unusual magnetic
structures, but also support unconventional excitations in many cases. Using a physically …

Neutron scattering measurements on the pyrochlore magnet Ce 2 Zr 2 O 7 reveal an
unusual crystal field splitting of its lowest J= 5/2 multiplet, such that its ground-state doublet …

The Ce 3+ pseudospin-1/2 degrees of freedom in the pyrochlore magnet Ce 2 Zr 2 O 7 are
known to possess dipole-octupole character, making it a candidate for novel quantum spin …

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 …

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 …

Recent theoretical proposals have argued that cobaltates with edge-sharing octahedral
coordination can have significant bond-dependent exchange couplings thus offering a …
