High-field magnetostriction measurements on the spin gap system KCuCl3 have been performed by using strain gauges in pulsed magnetic fields up to 55 T at 1.3 K. For H k the [0,1,0] direction, longitudinal magnetiostriction shows expansion and transverse magnetizations show shrinkage at the gap field Hg, at which finite magnetization appear. Both magnetostrictions saturate at the saturation field of magnetization. These results indicate a strong magnetoelastic coupling in KCuCl3.
