Fig. 3: Analysis of resistivities.
From: Thermodynamic evidence for polaron stabilization inside the antiferromagnetic order of Eu5In2Sb6

Ratio r of resistivities ρ measured along I∥a, H∥c versus I∥c, H∥b for fields μ0H = 0 T ( × ), 3 T (∘) and 9 T ( + ). The dotted line is a guide to the eye. Inset: individual ρ values; I∥a bluish, I∥c reddish for 0 T ( × ) and 3 T (∘). T+ marks the crossover into an inhomogeneous, polaronic state upon lowering T, here shown for H = 0.
