Times Cited Count:17 Percentile:56.61(Materials Science, Multidisciplinary)We investigated the iron-based ladder compounds (Ba, Cs)FeSe
, whose parent compounds, BaFe
Se
and CsFe
Se
, have different space groups, formal valences of Fe and magnetic structures. Electrical resistivity, specific heat, magnetic susceptibility, X-ray diffraction and powder neutron diffraction measurements were conducted to obtain the temperature and composition phase diagram of this system. Block magnetism seen in BaFe
Se
is drastically suppressed with Cs doping. In contrast, stripe magnetism observed in CsFe
Se
more resilient to Ba doping. Novel magnetic structure appears in intermediate compositions, which is similar to the stripe magnetism of CsFe
Se
but with different inter-ladder spin configuration. Intermediate compounds show insulating behavior, nevertheless finite T-linear contribution in specific heat was obtained at low temperature.

O,5n)
Rf reaction has been studied by anion-exchange chromatography on an atom-at-a-time scale. The anion-exchangechromatographic behavior of Rf was investigated in 1.9-13.9 M hydrofluoric acid together with those of the group-4 elements Zr and Hf produced in the
O-induced reactions on Ge and Gd targets, respectively. It was found that the adsorption behavior of Rf on anion-exchange resin is quite different from those of Zr and Hf, suggesting the influence of relativistic effect on the fluoride complexation of Rf.
