Spin-Charge Coupling in lightly doped NdCeCuO
Shiliang Li, Stephen D. Wilson, David Mandrus +4
We use neutron scattering to study the influence of a magnetic field on spin structures of NdCuO. On cooling from room temperature, NdCuO goes through a series of a…
Variation of Specific Heat with x and y in NaxCoO2-yH2O/D2O
R. Jin, B. C. Sales, S. Li +1
We report specific heat measurements down to 0.4 K on the layered oxide NaCoOHO/DO with 0 0.74 and = 0 and 1.4. For the non…
Magnetism in purple bronze LiMoO
J. Chakhalian, Z. Salman, J. Brewer +4
Muon spin relaxation measurements around the 25 K metal-insulator transition in LiMoO elucidate a profound role of disorder as a possible mechanism for this tran…
Fermi surface topology of Ca_{1.5}Sr_{0.5}RuO_{4} determined by ARPES
S. -C. Wang, H. -B. Yang, A. K. P. Sekharan +11
We report ARPES results of the Fermi surface of Ca_{1.5}Sr_{0.5}RuO$_{4}, which is at the boundary of magnetic/orbital instability in the phase diagram of the Ca-substituted Sr rut…
Four-well tunneling states and elastic response of clathrates
I. Zerec, V. Keppens, M. A. McGuire +3
We present resonant ultrasound elastic constant measurements of the clathrate compounds Eu8Ga16Ge30 and Sr8Ga16Ge30. The elastic response of the Eu clathrate provides clear evidenc…
Luttinger liquid ARPES spectra from samples of LiMoO grown by the temperature gradient flux technique
G. -H. Gweon, S. -K. Mo, J. W. Allen +4
Angle resolved photoemission spectroscopy line shapes measured for quasi-one-dimensional LiMoO samples grown by a temperature gradient flux technique are found t…
