Recentely we have measured (RB 1620263) pressure dependence of phonon modes in both the protonated (H2O) and deuterated ice (D2O) (Fig. 2) at ambient, 0.3 kbar, 1.0 kbar and 1.6... -
High-energy spin excitations in the optimally doped Ba0.67K0.33Fe2As2
From our previous data on BaFe2As2 and BaFe1.9Ni0.1As2, one may assume that the superconductivity only affects the low energy excitations. But for Ba0.67K0.33Fe2As2, the doping... -
