Inter-Cation Charge Transfer Mediated Antiferromagnetism in Co${}_{1+x}$Ir${}_{2-x}$S${}_4$

Liang-Wen Ji, Si-Qi Wu, Bai-Zhuo Li +6

The antiferromagnetism in transition metal compounds is mostly mediated by the bridging anions through a so-called superexchange mechanism. However, in materials like normal spinel…
