Abstract

We report here the two current topics in the ladder compounds. 1. The new ladder compound LaCuO_2.5 recently discovered by Hiroi and Takano shows a clear sign of magnetic long range order at around 125 K observed by μ⁺SR technique. This result demonstrates that the ground state of LaCuO_2.5 is not a spin liquid state, but a magnetically ordered state. 2. Superconductivity has been found in the ladder material (Sr, Ca)₁₄Cu₂₄O₄₁ under high pressure between 3 GPa and 4.5 GPa. The superconducting transition temperatures T_c (onset) are 12 K and 9 K at 3 GPa and 4.5 GPa, respectively.
