A Novel Strongly Spin-Orbit Coupled Quantum Dimer Magnet: Yb2Si2O7

Recently published in Physical Review Letters: The quantum dimer magnet (QDM) is the canonical example of “quantum magnetism”. We report our single crystal neutron diffraction, specific heat, and ultrasound velocity work on a new QDM in the strongly spin-orbit coupled, distorted

Gavin at ORNL for HB1A Experiment

Gavin Hester ran a neutron scattering experiment at the High Flux Isotope Reactor in Oak Ridge National Lab on beamline HB-1A, a triple-axis spectrometer.

Short-range order in the quantum XXZ honeycomb lattice material BaCo2(PO4)2

Recently published in Physical Review B: The magnetic honeycomb lattice with competing interactions can give rise to unconventional quantum phases.  We present observations of highly frustrated quasi two-dimensional (2D) magnetic correlations in the honeycomb lattice layers of the Seff =

Tuning the antiferromagnetic helical pitch length and nanoscale domain size in Fe3PO4O3 by magnetic dilution

We have investigated the effect of magnetic dilution (substituting Ga for Fe) on the partially ordered helical antiferromagnetic ground state of Fe3PO4O3.  The helical state in this compound is known to form in needle-like domains, with short range correlations in

Gavin Hester wins poster prize

Single-ion properties of the S = 1/2 XY antiferromagnetic pyrochlores, NaA’Co2F7 (A’ = Ca2+, Sr2+)

Our paper on the single ion properties of Cobalt-based S=1/2 pyrochlores NaCaCo2F7 and NaSrCo2F7 was published in PRB as an editors suggestion.  Based on inelastic neutron scattering, from which we can extract the single ion angular momentum wavefunctions and thus
