Anomalous lattice dynamics of the elemental superconductor niobium
Phonon lifetimes in BCS superconductors provide information on the details of the electron-phonon coupling mechanism. In 2008 high-resolution neutron inelastic scattering... -
Magnetic excitations of heavily electron overdoped BaFe0.8Ni1.2As2
We have devoted much efforts to investigating the doping evolution of the magnetic excitations in electron doped BaFe2-xNixAs2 (x=0-0.6). Spin excitations for x=0-0.6 have been...
