| (a) H-T phase diagram, which exhibits a PM, an AFM, and a FM phase, extracted from various M(H) and M(T) curves. The hysteretic region where either FM or AFM can be stabilized is hatched. Arrows across phase lines indicate for which measurement direction it is observed given the hysteresis. Spin structure in C2/m cell of the AFM (b) and FM phase (c). Gray arrows indicate bilayer net magnetization |
