High-pressure NMR measurements on a single crystal of hole-doped two-leg la
dder compound, Sr2Ca12Cu24O41, have been carried out up to similar to 1.7 G
Pa. 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
