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 …

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 …

We report the synthesis of powder and single-crystal samples of cerium pyrohafnate and
their characterization using neutron diffraction, thermogravimetry and x-ray absorption …

The structural and compositional diversity of the RTX 3 family of materials offers various
magnetic and thermodynamic properties such as complex magnetic structure, vibronic …

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 …

Nearly a century of research has established the Born–Oppenheimer approximation as a
cornerstone of condensed-matter systems, stating that the motion of the atomic nuclei and …

Phonon softening is a common identifier of strong coupling between electronic and
vibrational degrees of freedom in materials, which is responsible for many of the exotic …

We present a systematic study of the crystal-field interactions in the Li RF 4 (R= Gd, Ho, Er,
Tm, and Yb) family of rare-earth magnets. Using detailed inelastic neutron scattering …

The single-ion physics of Ho 2 Ti 2 O 7 is well understood to produce strong Ising
anisotropy, which is an essential ingredient to its low-temperature spin-ice state. We present …

CsYbSe2, a recently identified quantum spin liquid (QSL) candidate, exhibits strong crystal
electric field (CEF) excitations. Here, we identify phonon and CEF modes with Raman …
