Abstract

Appearance of the field-induced long-range ordering was observed directly by a proton NMR measurement in Haldane gap system, Ni(C₅H ₁₄N₂)₂N₃(PF₆) (NDMAP). A sudden splitting of the spectrum due to the appearance of the transverse staggered moment was observed just below T_N. The transverse staggered moment is estimated as 1.1 μB in the external field of 10.9 T parallel to the ab-plane.
