Abstract

We report on H-1 NMR of (NixMn1-x)(3)[Cr(Cn)(6)](2) center dot nH(2)O hexacyanochromates, where x changes from 0 to 1. The decay time constants of the free induction decay signals described by an effective spin-spin relaxation time T-2eff obtained from M(t) = M-0 exp(t/T-2eff) decrease as the local magnetic moments increase produced by the magnetic transition metal ions at the sites of the resonant H-1 nuclei. The recovery of the magnetization in the spin-lattice relaxation time (T-1) experiments was single-exponential.
