Abstract

57Fe Mössbauer and magnetometric studies of the molecular ferrimagnet N(n-C5H11)4 [ FeIIFeIII(C2O4)3] are indicative of a 2D magnetic character with strong uniaxial anisotropy in the basal plane of the crystal. It is established that the change in the sign of the net magnetization of this compound is related to a compensation between FeIII and FeII sublattice magnetizations at Tcomp=31.2 K. The form and parameters of the magnetic Hamiltonian describing the temperature dependence of the FeIII sublattice and the net magnetizations are determined.
