Abstract

Cu-NMR study has been performed on the disordered spin-gap system Tl 1-xKxCuCl3 In the high-field H > H C Δ/μB, where Δ is the spin-gap, the hyperfine field becomes extremely inhomogeneous at low temperatures due to the field-induced magnetic order, indicating that the ordered spin state must be different from the pure TlCuCl3. In the low field H < H C, a saturating behavior in the longitudinal nuclear spin relaxation rate T-11was observed at low temperatures, indicating existence of the magnetic ground state proposed to be Bose-glass phase by Fisher.
