Abstract

The 1H NMR spin-lattice relaxation time T1 in a spin 1/2 1-D antiferromagnetic complex [NiBr(chxn)2]Br2 was observed down to 1.8 K. The observed T1 temperature dependence was well reproduced by the Sachdev's treatment giving an exchange interaction energy (J) of ca. 2500K. 1-D spin migration assignable to paramagnetic electrons in impurity amounts of NiII sites was observed at low temperatures.
