Structural and magnetic studies of the alkali sesquioxides Rb4O6 and Cs4O6
The mixed-valence sesquioxides A4O6 (A = alkali metal) are particularly intriguing magneticmaterials comprising of non-magnetic (O2)2- and magnetic (O2)- anions. Recent... -
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...
