摘要：

We have performed muon spin relaxation measurements of the spin-ladder cuprates Srn-1Cun+1O2n (n=3,5). The 3-leg ladder system (n=5) shows static magnetic order at T∼52 K, which is between the ordering temperatures of the one-dimensional chain system Sr2CuO3 (TN∼5 K) and of the two-dimensional layer system Ca0.86Sr0.14CuO2 (TN∼540 K). The 2-leg ladder system (n=3) does not show any magnetic order down to 20 mK, in agreement with the theoretical prediction of a nonmagnetic ground state with a spin gap for even-leg-number ladder systems. © 1995 The American Physical Society.
