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 Ni^II sites was observed at low temperatures.
