From: High-temperature ferrimagnetic order triggered metal-to-insulator transition in CaCu3Ni2Os2O12

Temperature dependence of (a) magnetic susceptibility χ and its inverse measured at 0.1 T, b the isothermal magnetization loops measured at different temperatures. The black curve in (a) shows the Néel FiM model fitting for χ–1 above 400 K.
