1H-NMR Study on the Magnetic Order in the Mixture of Two Spin Gap Systems (CH3)2CHNH3CuCl3 and (CH3)2CHNH3CuBr3

The antiferromagnetic ordering in the solid-solution of the two spin-gap systems (CH 3 ) 2 CHNH 3 CuCl 3 and (CH 3 ) 2 CHNH 3 CuBr 3 has been investigated by 1 H-NMR. The sample with the Cl-content...
