Resumen

A structural and thermodynamic study of the newly synthesized single crystal Sr₅Rh₄O₁₂ is reported. Sr ₅Rh₄O₁₂ consists of a triangular lattice of spin-chains running along the c-axis. It is antiferromagnetically ordered below 23 K with the intrachain and interchain coupling being ferromagnetic (FM) and antiferromagnetic (AFM), respectively. There is strong evidence for an Ising character in the interaction and geometrical frustration that causes incomplete long-range AFM order. The isothermal magnetization exhibits two steplike transitions leading to a ferrimagnetic state at 2.4 T and a FM state at 4.8 T, respectively. Sr₅Rh₄O₁₂ is a unique frustrated spin-chain system ever found in 4d and 5d-based materials without a presence of an incomplete 3d-electron shell.
