  1. Our values are obtained within the quasi-atomic approximation (DFT + HubI), as well as with the Kondo effect included using DMFT(QMC). Theoretical DFT values from refs. 18 (a) and 19 (b) are obtained with Ce-4f treated as valence states. DFT calculations of ref. 17 (c) treated Ce-4f as open core. Experimental values are from this work, as well as from previous measurements of refs. 20, 21, and 4 that are indicated by superscripts d, e, and f, respectively. The experimental values in ref. 20 (d) are for CeFe11TiN1.5. The low-temperature values in ref. 21 (e) are for 1.5 K; we extracted their HA from the magnetization curves shown in Fig. 3 of this reference.
