In spin-ice research, small variations in structure or interactions drive a multitude of different behaviors, yet the collection of known materials relies heavily on the ``227'' pyrochlore structure. Here, we present thermodynamic, structural, and inelastic-neutron-scattering data on a spin-ice material, ${\mathrm{MgEr}}_{2}{\mathrm{Se}}_{4}$, which contributes to the relatively underexplored family of rare-earth spinel chalcogenides. X-ray and neutron diffraction confirm a normal spinel… 

Neutron scattering measurement of crystalline-electric fields in magnesium rare-earth selenide spinels

The symmetry of local moments plays a defining role in the nature of exotic grounds states stabilized in frustrated magnetic materials. We present inelastic neutron scattering (INS) measurements of

Orientation-dependent stabilization of MgCr2O4 spinel thin films

$A{B}_{2}{\mathrm{O}}_{4}$ normal spinels with a magnetic $B$ site can host a variety of magnetic and orbital frustrations leading to spin-liquid phases and field-induced phase transitions. Here, we

Frustrated magnetism in fluoride and chalcogenide pyrochlore lattice materials

Pyrochlore lattices, which are found in two important classes of materials -- the $A_2B_2X_7$ pyrochlore family and the $AB_2X_4$ spinel family -- are the quintessential 3-dimensional frustrated

Effective point-charge analysis of crystal fields: Application to rare-earth pyrochlores and tripod kagome magnets R3Mg2Sb3O14

The authors describe a method to analyze crystal field excitation spectra using adjustable effective point-charges and apply to two families of materials.



Single-ion anisotropy and magnetic field response in the spin-ice materials Ho2Ti2O7 and Dy2Ti2O7

Motivated by its role as a central pillar of current theories of the dynamics of spin ice in and out of equilibrium, we study the single-ion dynamics of the magnetic rare-earth ions in their local

Candidate quantum spin ice in the pyrochlore Pr 2 Hf 2 O 7

We report the low temperature magnetic properties of the pyrochlore ${\mathrm{Pr}}_{2}{\mathrm{Hf}}_{2}{\mathrm{O}}_{7}$. Polycrystalline and single-crystal samples are investigated using

Dipolar Spin Ice States with a Fast Monopole Hopping Rate in CdEr_{2}X_{4} (X=Se, S).

This work suggests that CdEr_{2}X_{4} offer the possibility to study alternative spin ice ground states and dynamics, with equilibration possible at much lower temperatures than the rare earth pyrochlore examples.

Magnons and a two-component spin gap in FeV2O4

The spinel vanadates have become a model family for exploring orbital order on the frustrated pyrochlore lattice, and recent debate has focused on the symmetry of local crystal fields at the cation

Spin dynamics of the ordered dipolar-octupolar pseudospin- 1 / 2 pyrochlore Nd 2 Zr 2 O 7 probed by muon spin relaxation

We present a muon spin relaxation study on the Ising pyrochlore ${\mathrm{Nd}}_{2}{\mathrm{Zr}}_{2}{\mathrm{O}}_{7}$ which develops an ``all-in-all-out'' magnetic order below 0.4 K. At 20 mK, far

Our polycrystalline sample study on the Yb-based chalcogenide spinels $A{\mathrm{Yb}}_{2}{X}_{4}$ ($A=$ Cd, Mg; $X=$ S, Se) has revealed frustrated magnetism due to the antiferromagnetically coupled

Quantum fluctuations in the effective pseudospin- 1 2 model for magnetic pyrochlore oxides

The effective quantum pseudospin-$1/2$ model for interacting rare-earth magnetic moments, which are locally described with atomic doublets, is studied theoretically for magnetic pyrochlore oxides. It

Magnetic order and ice rules in the multiferroic spinel FeV 2 O 4

We present a neutron-diffraction study of FeV2O4, which is rare in exhibiting spin and orbital degrees of freedom on both cation sublattices of the spinel structure. Our data confirm the existence of
