Abstract
We report here the two current topics in the ladder compounds. 1. The new ladder compound LaCuO2.5 recently discovered by Hiroi and Takano s hows a clear sign of magnetic long range order at around 125 K observe d by mu(+)SR technique. This result demonstrates that the ground state of LaCuO2.5 is not a spin liquid state, but a magnetically ordered st ate. 2. Superconductivity has been found in the ladder material (Sr,Ca )(14)Cu24O41 under high pressure between 3 GPa and 4.5 GPa. The superc onducting transition temperatures T-c (onset) are 12 K and 9 K at 3 GP a and 4.5 GPa, respectively.
