摘要：

We have measured the Mossbauer effect of Fe-57(3+) (S = 5/2) ions doped in a 1D Ising ferromagnet Ca3Co2O6. The spectra with hyperfine fields corresponding to the exchange polarized Fe electron spins with m(z) = +/-5/2, +/-3/2, +/-1/2 are first observed in the magnetically dense system for T less than or equal to 20 K, suggesting slow magnetic relaxation at the Fe3+ sites. The key lies in the large difference between magnetic characters of the host (Ising) and impurity (Heisenberg) spins, making the impurity spins extremely isolated in the host 1D Ising spin system.
