摘要翻译:
用1H-NMR研究了(CH3)2CHNH3CuCl3和(CH3)2CHNH3CuBr3两个自旋带系固溶体中的反铁磁有序性。Cl含量比x=0.85的样品在Tn=13.5K以下谱线出现明显的分裂,自旋晶格弛豫速率T1-1出现发散行为。超精细场与温度相关的临界指数为0.33。

英文摘要:
The antiferromagnetic ordering in the solid-solution of the two spin-gap systems (CH3)2CHNH3CuCl3 and (CH3)2CHNH3CuBr3 has been investigated by 1H-NMR. The sample with the Cl-content ratio x=0.85 showed a clear splitting in spectra below TN=13.5 K, where the spin-lattice relaxation rate T1-1 showed a diverging behavior. The critical exponent of the temperature dependence of the hyperfine field is found to be 0.33.
