Extended Data Fig. 4: Extracting ΔM from κ(B) in R2G.
From: Fluctuating magnetism and Pomeranchuk effect in multilayer graphene
a, High-resolution measurement of κ = ∂μ/∂ne for in-plane fields of 0 and 4 T at D = 0.5 V nm−1 and T = 1.5 K. b, \({{\rm{d}}}^{2}M/{\rm{d}}{n}_{{\rm{e}}}^{2}=-\,\Delta \kappa /\Delta B=-\,(\kappa ({B}_{{\rm{H}}})-\kappa ({B}_{{\rm{L}}}))/\Delta B\) measured for BH = 4 T and BL = 0 T. c, Data from panel b integrated with respect to |ne| to give dM/dne. d, Data from panel c integrated with respect to |ne| to give ΔM. The detailed analysis process is described in Methods.
