Extended Data Fig. 1: Extraction of the Spontaneous Nernst effect.
From: State with spontaneously broken time-reversal symmetry above the superconducting phase transition
Temperature dependence of the Nernst (left axis) and Seebeck (right axis) signals for x = 0.8 and B = 2 T. The green full and empty symbols represent the Nernst signal for B = 2 T and B = − 2 T, respectively. The red and blue lines represent the evaluated B-antisymmetric and B-symmetric parts of the Nernst signal, respectively. The black dashed line represents the Seebeck signal for B = 2 T. Inset: Spontaneous Nernst effect at B = 2 T, extracted according to Eq. (1).
