When manganese atoms partition into austenite, three magnetic structures [28] of γ-FeMn have been proposed, including a collinear antiferromagnetic (1Q) (Fig. 7 (b)) and two noncollinear (2Q and 3Q) antiferromagnetic configurations (Fig. 7 (c-d)). In the 1Q configuration, the magnetic moments of manganese and Fe are collinear.
