Magnetic characterization. a Temperature dependence of χMT and χM−1 for [Fe14] (Hdc = 100 Oe). The black symbol is the experimental data and the red line is the fitting result. b Magnetization vs. external magnetic field curve for [Fe14] at 2 K. The blue line corresponds to the calculated Brillouin function for S = 14 (J → +∞). The red line represents the sum of the Brillouin functions that correspond to four magnetically isolated S = 5/2 and two S = 2 (J = 0). The green line represents the simulated curve that includes weak ferromagnetic coupling between B sites (J = 0.9 K, g = 2.0). c Top: the left and right circularly polarized L3-edge total fluorescence yield spectra of the [Fe14] complex (14 T, 3.5 K). Bottom: the field dependence of the [Fe14] L3-edge XMCD spectra (left–right) measured at 3.5 K. d Magnetic susceptibility under a 50 Oe field in the temperature region of 50–0.5 K. e The field-dependent heat capacity of [Fe14] from 0 to 9 T in the temperature region of 100–0.36 K.
