Abstract

We investigated the iron-based ladder compounds (Ba, $Cs) {Fe}_{2} {Se}_{3}$ . Their parent compounds ${BaFe}_{2} {Se}_{3}$ and ${CsFe}_{2} {Se}_{3}$ 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 a temperature and composition phase diagram of this system. Block magnetism observed in ${BaFe}_{2} {Se}_{3}$ is drastically suppressed with Cs doping. In contrast, stripe magnetism observed in ${CsFe}_{2} {Se}_{3}$ is not so fragile against Ba doping. A new type of magnetic structure appears in intermediate compositions, which is similar to stripe magnetism of ${CsFe}_{2} {Se}_{3}$ , but interladder spin configuration is different. Intermediate compounds show insulating behavior, nevertheless a finite $T$ -linear contribution in specific heat was obtained at low temperatures.
