Tuning ferromagnetism and spin state in La(1−x)AxCoO3 (Prakash1, Shukla2, Nehla3 et al. 2018Journal of Alloys and Compounds

“…If such a splitting is sufficient, then an IS state might be achieved without a JT distortion [25]. It has been shown that monoclinic/rhombohedral distortion affects the electronic structure and orbital orderingdriven ferromagnetism in LaCoO 3 [26][27][28]. Yan et al observed the ferromagnetism in LaCoO 3 , which demonstrated to be due to the coupling between the surface Co +3 ions [29].…”

First-principles study of crystal and electronic structure of rare-earth cobaltites

“…3 There are six 3d electrons in the Co 3+ ions of RCoO 3 perovskite and hence the possible electron spin states are S=0, 1, 2, conventionally referred to as low-spin (LS; t 6 2g e 0 g ), intermediate-spin (IS; t 5 2g e 1 g ) and high-spin (HS; t 4 2g e 2 g ), respectively. This is atomic-like language, however, which is not a fully appropriate description, 20 a point that will be returned to below.…”
