The antiferromagnetic ordering in the solid-solution of the two spin-gap systems (CH ₃) ₂CHNH ₃CuCl ₃ and (CH ₃) ₂CHNH ₃CuBr ₃ has been investigated by ¹H-NMR. The sample with the Cl-content ratio x = 0:85 showed a clear splitting in spectra below T _N = 13:5 K, where the spin-lattice relaxation rate T ₁ ^-1 showed a diverging behavior. The critical exponent of the temperature dependence of the hyperfine field is found to be 0.33.
