Fig. 4: Pressure evolution of the AFM suppression field.
From: Non-monotonic pressure dependence of high-field nematicity and magnetism in CeRhIn5
MR (left) and its second derivatives (right) recorded at various temperatures for sample 1 at (a, b) ambient pressure, and (c, d) p = 12 kbar for both current directions, I∣∣a and I∣∣b*; the latter has a lower resistivity at high field due to contributions of c-axis resistivity (see text). Magenta shading indicates nematic region. Green rectangles mark a discontinuity in the slope associated with the AFM suppression field Bc, which appears as a maximum/minimum in the 2nd derivative, depending on the transport direction and temperature.
