Abstract
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.
