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 …

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 …

We apply moderate-high-energy inelastic neutron scattering (INS) measurements to
investigate Yb 3+ crystalline electric field (CEF) levels in the triangular spin-liquid candidate …

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 …

The frustrated pyrochlore magnet Yb 2 Ti 2 O 7 has the remarkable property that it orders
magnetically but has no propagating magnons over wide regions of the Brillouin zone. Here …

We propose a systematic method to generate a complete orthonormal basis set of multipole
expansion for magnetic structures in arbitrary crystal structure. The key idea is the …

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 …

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 …

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 …

Recently there have been a number of experiments on Ce 2 Zr 2 O 7 and Ce 2 Sn 2 O 7,
suggesting that these materials host a three-dimensional quantum spin liquid with emergent …
