dc.description.abstractThe magnetic characteristics of the molecular magnet [Fe-II(Delta)Fe-II(Lambda)(ox)(2)(Phen)(2)](n), having chemical formula C28H16Fe2N4O8 for unity, has been studied by magnetization, neutron diffraction, and field-dependent specific heat-measurements. In the high-temperature regime (T>T-m), the one-dimensional Ising chain model with alternate Lande factors is applied to describe its quasiferrimagnetic behavior as temperature approaches T-m. In the low-temperature region (T < T-m), the increase of interchain interactions gives rise to long-range magnetic ordering as indicated by an anomaly in specific heat. Furthermore, an intrinsic antiparallel alignment of spins with a net ferrimagnetic structure is deduced from neutron diffraction study. The field-dependent lambda-type anomaly of specific heat indicates that applying a magnetic field raises magnetic ordering temperature. An additional small anomaly in specific heat is also seen below T-m, which could be due to the zero-field splitting caused by the internal crystal field.en_US
