Table 1 Qualitative comparison between different scenarios and measured MFM contrast.

T	H	Conventional AFM transition		Zener polaron scenario		Short-range AFM correlation scenario		Measured contrast
T	H	Spin alignment	Contrast	Spin alignment	Contrast	Spin alignment	Contrast	Measured contrast
T_COI	0		None		None		None
	Low		None		Weak		Weak	Weak
	High		None		Weak		Strong	Strong
T_N	High		Strong		Strong		None/weak	None

The rectangular regions, filled with arrows and different colors represent the different phases. The gray, red, orange, and green regions are the paramagnetic, CE, Zener polaron PM, and short-range AFM-correlated phases, respectively.
