Abstract

Magnetization has been calculated as a function of temperature in the ferromagnetic phase of (CH3)(2)NH2Na0.5Fe0.5(HCOO)(3)denoted by DMNaFe as one of the metal formate framework by using molecular field theory. CalculatedM(T) is compared with the magnetization measured as a function of temperature (H = 10 Oe) in field-cooling and zero-field-cooling regimes from the literature, and a power-law analysis of the experimental data was performed for DMNaFe. Magnetization measured as a function of the magnetic field, as reported in the literature, has also been analyzed by the power-law formula. The magnetization indicates a weak first-order (or nearly second-order) ferromagnetic transition in DMNaFe.
