The Jacob's ladder of density functional theory (DFT) proposes the compelling view that by extending form successful approximations-being guided exact conditions and selected (least empirical) norms-upper rungs will do better than lower, thus allowing to balance accuracy computational effort. Meta-generalized gradient approximations (MGGAs) belong last rung semilocal before hybridization with nonlocal wave function theories. Among MGGAs, strongly constrained appropriately normed approximation (SCAN) greatly improves upon GGAs from lower rung. But over magnetized solutions SCAN make more reliable for magnetism. Here, we provide a solution satisfies most pressing desiderata ferromagnetic, antiferromagnetic noncollinear states. approach is available in an implementation crystal electronic structure package.
