a Temperature dependence (T) of magnetization (M) under the DC applied magnetic field (HDC) of 0.1 T. A smaller HDC than Hs is chosen so as to stress the ferrimagnetic character (Supplementary Fig. 4). b HDC dependence of M at 2 K. Inset shows Gd content (x) dependent Hs. c TC (black dots) and μeff. (red dots) of [Y2−xGdxC]2+·2e− as a function of Gd content (x). The black and red dashed lines are guides to show the monotonical changes of the TC and μeff. values. The first-derivative plots of M–T curves to determine the TC are provided in Supplementary Fig. 5. The μeff. values are obtained from the saturation magnetization in b. d M−1–T plots. Black dashed lines are Curie–Weiss fits. The arrows indicate the deviations from the Curie–Weiss law for each sample. The most significant deviation is found for x = 0.93 (Enlarged figure is seen in Supplementary Fig. 6b).
