摘要

Two [FeLn_2Fe(m_3-OH)_2(teg)_2(N_3)_2(C_6H_5COO)_4] compounds (where Ln=Y~(III) and Dy~(III); teg=triethylene glycol anion) have been synthesized and studied using SQUID and M?ssbauer spectroscopy. The magnetic measurements on both compounds indicate dominant antiferromagnetic interactions between the metal centers. Analysis of the ~(57)Fe M?ssbauer spectra complement the ac magnetic susceptibility measurements, which show how a static magnetic field can quench the slow relaxation of magnetization generated by the anisotropic Dy~(III) ions.
