Detecting an entanglement transition in a quantum magnet
Justification: We'd like to apply for three days Director’s Discretionary time on WISH to continue the experiment on measures of quantum entanglement in a model 1D magnet. This... -
High Energy Spin Fluctuations in YFe2Ge2
The recently discovered superconductor YFe2Ge2 (Tc about 1.8K) has the same crystal structure as 122 iron-based superconductors, with no static magnetic order be reported.... -
Magnetic excitations from optimally doped BSCCO in the pseudogap phase
We plan to study the temperature dependence of magnetic excitations in the optimally doped high-Tc superconductor Bi$2$Sr$_2$CaCu$_2$O${8+\delta}$ (BSCCO). We have previously... -

Spin excitation as a probe of electron correlation strength in over doped BaF...
Evidence is building that iron pnictides inhabit the mostly unexplored ¿intermediate¿ region of electronic correlation strength, which is neither very weak coupling, nor strong... -
Crystal and magnetic structure of the polar ferrimagnet BaCaFe4O7
Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices; the inherent magnetoelectric effect can underpin both pyroelectric or... -
Multimagnon and intra-band excitations in the Spin-1 Haldane chain
The spin-1 Heisenberg antiferromagnetic (HAFM) chain is a canonical model system in quantum magnetism. The existence of the Haldane gap to the lowest energy excitations has been... -

Spin excitation anisotropy in FeSe
Iron selenide (FeSe), a member of "11" family in iron-based superconductors, does not have static AF order; thus, the structural transition and associated nematic order have... -

Study of frustration and the anomalous Hall effect in Fe3Sn2
We have found unusual and promising Hall effect behaviour in the alloy Fe3Sn2 at 300K. Fe3Sn2 is predominantly ferromagnetic, however, our neutron diffraction data indicate that... -
Gaps in the spin wave dispersion relation in elemental iron
Iron is a canonical instance of an itinerant electron ferromagnet, and a classic correlated electron system. Our recent data from MAPS contradicts earlier triple-axis data that... -
Spectral signatures of the magnetically hidden octupolar order in Sr2VO4
We propose to study low-energy magnetic excitations associated with the low-temperature ordered phase in polycrystalline Sr2VO4. This layered perovskite compound exhibits an... -
