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 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.
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 =…
Aaron and Andrew at our first successful test of the RUS probe in the PPMS
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…
Graduate student Gavin Hester won a poster prize at the SNS/HFIR User Group Meeting at Oak Ridge National Laboratory in July 2017. Well done, Gavin!
Undergraduate researcher Tyler Dodge has won prizes this year at two conferences (Front Range Advanced Magnetics Symposium 2016, and the APS Four Corners section meeting 2016) for his poster that described developing the Resonant Ultrasound Spectroscopy probe. Well done, Tyler!
Undergraduate researcher Tim Reeder won a prize for an excellent oral presentation that he gave at the Magnetics workshop held at CSU in the fall of 2016. Well done, Tim!

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…
