Theoretical and experimental aspects of a class of new cupric oxides called spin ladder coumpounds will be summarized, where the ladders are made from antiferromagnetic chains of S=1/2 spins by connecting them together with inter-chain antiferromagnetic bonds. Hole carriers doped into evenleg ladders have been predicted to pair, and possibly superconduct. By means of high pressure synthesis at 3-6 GPa and 1200 K, typically, two kinds of 2-leg ladder compounds SrCu<SUB>2</SUB>O<SUB>3</SUB> and LaCuO<SUB>2. 5</SUB> and a 3-leg ladder compound Sr<SUB>2</SUB>Cu<SUB>3</SUB>O<SUB>5</SUB> have been prepared. Their magnetic and electrical properties will be compared with theoretical predictions.
