Reevaluating Quantum Geometric Criteria for Itinerant Magnetic Instabilities
Magnetic instabilities in generic two-orbital systems are governed by the full interplay of the bare susceptibility tensor and spin interaction matrix, not solely by the quantum geometry of a single-channel susceptibility.
