摘要：

High-pressure NMR measurements on a single crystal of hole-doped two-leg ladder compound, Sr(2)Ca(12)Cu(24)O(41), have been carried out up to similar to 1.7 GPa. The activated T-dependences of T(1) and Knight shift at 1.7 GPa assured the persistence of the spin gap in this system. (C) 1998 Elsevier Science B.V, AII rights reserved.
