CeRh6Ge4, a cerium-based ferromagnetic material, exhibits quantum critical behavior under pressure, posing intriguing questions about its magnetic interactions. Here, the authors use density functional theory combined with dynamical mean-field theory to reveal the formation of isotropic spin chains along the c axis that are coupled by anisotropic inter-chain interactions, elucidating the material’s ferromagnetic transition and quantum criticality.
