An understanding of how quantum spin liquids arise in frustrated magnets at low temperatures remains elusive. Here the authors demonstrate a pressure-driven ferromagnetic transition out of a quantum spin liquid phase in the pyrochlore Yb2Ti2O7, highl

Spin 1/2 dimer systems in an external magnetic field behave as a lattice gas of hard-core bosons, and can undergo condensation. Here the authors show in SrCu2(BO3)2that new fractionally crystallized states are not only possible, but also tuneable wit

The transverse field Ising chain model is ideally suited for testing the fundamental ideas of quantum phase transitions because its well-known T=0 ground state can be extrapolated to finite temperatures. Nonetheless, the lack of appropriate model mat

We present a detailed magnetic study of the triangular antiferromagnet ${\mathrm{ErMgGaO}}_{4}$. A point charge calculation under the single ion approximation reveals a crystal field ground state doublet with a strong Ising-like behavior of the ${\ma

Frustrated magnets provide an exciting playground for the study of exotic magnetic properties. Here, the authors use a combination of neutron scattering and muon spin rotation to determine crystal electric fields, spin anisotropy, and the magnetic st

A previously unidentified polymorph of nickel niobate, NiNb2O6, was grown and stabilized in single crystalline form using an optical floating zone furnace. Key parameters of the growth procedure involved use of a slight excess of NiO (1.2% by mol), a

Extensive thermal conductivity measurements have been conducted on two single crystals of ${\mathrm{Dy}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$ from 60 mK to 60 K. The samples are differentiated by their levels of disorder, which are determined throug

The pyrochlore magnet ${\mathrm{Yb}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$ has been proposed as a quantum spin ice candidate, a spin liquid state expected to display emergent quantum electrodynamics with gauge photons among its elementary excitations
