Abstract
We investigate by means of ab initio electronic structure analysis and quantum Monte Carlo calculations the scenario where longer-ranged magnetic interactions dominate over short-ranged interactions in the physical description of compounds. This question is discussed, in particular, for the case of CaCuGe2O6 which shows a spin-singlet behavior induced by third-nearest-neighbor copper pairs.
