Phase Diagram of Ba1-xKxFe2As2
In the new class of iron pnictide superconductors, there is evidence of phase coexistence close to the phase boundary between the SDW and superconducting order produced by hole... -
Incommensurate magnetic fluctuation in KFe2As2
The debate whether interband or intraband scattering is crucial for Fe-based superconductors is not settled down yet. Investigation a system with completely missing electron... -
Incommensurate magnetic fluctuation in KFe2As2 at high energy
We clearly observed incommensurate (IC) magnetic excitation in KFe2As2 above Tc with Ei=80 mev on ARCS at ORNL. Though we got beam time at LET, we wish to see how the IC changes...
