Table 2. Comparison of the derived magnetic moments of the Fe- and Cr-ions and the total magnetic moment per formula unit (in units of the Bohr magneton μ_B) from neutron diffraction (ND), x-ray spectroscopy (XPS), magnetization measurements (Mag.), and theoretical approaches (Calc.) for lowest temperatures.
