First principles calculation and experimental investigation of lattice dynamics in the rare earth pyrochlores R2Ti2O7 (R=Tb, Dy, Ho)
M Ruminy, M Nunez Valdez, B Wehinger +15
We present a model of the lattice dynamics of the rare earth titanate pyrochlores R2Ti2O7 (R=Tb, Dy, Ho), which are important materials in the study of frustrated magnetism. The ph…
Sample independence of magnetoelastic excitations in the rare earth pyrochlore Tb2Ti2O7
M. Ruminy, L. Bovo, E. Pomjakushina +6
Recent experimental results have emphasized two aspects of Tb2Ti2O7 which have not been taken into account in previous attempts to construct theories of Tb2Ti2O7: the role of small…
Magnetoelastic excitations in the pyrochlore spin liquid TbTiO
T. Fennell, M. Kenzelmann, B. Roessli +9
At low temperatures, TbTiO enters a spin liquid state, despite expectations of magnetic order and/or a structural distortion. Using neutron scattering, we have discover…
MgB2 Energy Gap Determination by Scanning Tunneling Spectroscopy
T. W. Heitmann, S. D. Bu, D. M. Kim +13
We report scanning tunneling spectroscopy (STS) measurements of the gap properties of both ceramic MgB2 and c-axis oriented epitaxial MgB2 thin films. Both show a temperature depen…
beta-Cu3V2O8: Magnetic ordering in a spin-1/2 kagome-staircase lattice
N. Rogado, M. K. Haas, G. Lawes +3
The spin-1/2 Cu2+ ions in beta-Cu3V2O8 occupy the sites of a Kagome-staircase lattice, an anisotropic variant of the Kagome net: buckled layers and imbedded plaquettes of three edg…
Structure and Superconductivity in Zr-Stabilized, Nonstoichiometric Molybdenum Diboride
L. E. Muzzy, M. Avdeev, G. Lawes +5
The structure and physical properties of the Zr-stabilized, nonstoichiometric molybdenum diboride superconductor are reported. Good quality material of the diboride structure type…
