Giant Spin Magnetization from Quantum Geometry in Altermagnets
Centrosymmetric altermagnets exhibit giant magnetic-field-induced spin magnetization of order 10^{-2} μ_B nm^{-3} at ~10 mT, controlled solely by the spin-rotation quantum metric as the only symmetry-allowed linear quantum-geometric response.
