“…However, these levels can be further split by the exchange field of the moments and/or the internal field of the 3d and 4f moments. 13,14,[27][28][29][30][31] Below 1.8 K, C / T increases logarithmically and tends to saturate at further low temperature at ␥ ϳ 200 mJ/ mol-K 2 . This enhancement might indicate the presence of strong correlations between the Ce ions in the Co-dominated ferromagnetic ground state.…”

“…The Ce-O distances are almost the same as the one of CeO 2 , 2.36Å (discrepancy is 0.85%) [48], while the Ce-S2(Ce-As) distance is about 7% (10%) longer than the Ce-S (Ce-As) distance in a rocksalt CeS (CeAs), 2.89Å (3.04Å) [49,50]. These facts suggest that the Ce-O interactions are the same order in both polycrystalline CeOBiS 2 and CeFeAsO, and the Ce-S and Ce-As interactions are relatively weaker than the Ce-O interactions in the view points of the bond length.…”

“…The partial derivatives @SðTÞ @T ¼ C V ðTÞ T and @UðSðTÞÞ @T ¼ C V ðTÞ are given by Eqs. (17) and (18) for verifying and confirming the derivative (22). To determine the temperature by applying (22) the occupation numbers of the different states must necessarily be given by the occupation numbers (7) and (8) in thermal equilibrium.…”
