(a) Temperature-dependent susceptibility and effective magnetic moment (inset) of Fe(H2cit)(H2O)n material measured in a magnetic field of μ0H = 0.1 T. The full orange line (100–300 K) fits with Curie–Weiss law and the full blue line (5–300 K) fits for a chain of Fe2+ ions, as described in the text. (b) Isothermal magnetization M(H) measured at 2 K. |
