Fig. 5: Non-linear behavior of Δ with the magnetic field.
From: Evidence for ground state coherence in a two-dimensional Kondo lattice
a Plot of Δ as a function of Bz for a series of dI/dV spectra taken consecutively in the SoD cluster shown in the inset. The red dashed line is the linear fit realized in the 1 T < Bz < 11 T. The green shadow indicates the range of BZ where Δ deviates from a linear relation. The insert shows the SoD (encircled) where the data were taken. b Zoom-in of the boxed region in (a). The gray region indicates the uncertainty band of Δ in the linear region (see SI). c Plot of Δ as a function of Bz for a series of dI/dV spectra taken consecutively in the range ±11 T. The red dashed lines are the linear fits. d Zoom-in of the boxed region in (c). e Histogram showing the occurrence of \(\left|S\right|\) for the different SoD clusters explored within 0 T < Bz < 11 T.
