| description | Strange metals possess transport properties that are markedly different from those of a conventional Fermi liquid. Despite strong similarities in behavior exhibited by distinct families, a consistent description of strange metallic transport and, in particular, its evolution from low to high magnetic field strength H, is still lacking. The electron nematic FeSe_{1−x}S_{x} is one such strange metal displaying anomalous H/T scaling in its transverse magnetoresistance as well as a separation of transport and Hall lifetimes at low H beyond its (nematic) quantum critical point at x_{c}∼0.17. Here we report a study of the Hall response of FeSe_{1−x}S_{x} across x_{c} in fields up to 33 T. Upon subtraction of a normal H-linear component from the total Hall response (imposed by perfect charge compensation), we find a second component, ascribable to strange metal physics, that grows as 1/T upon approach to the quantum critical point. Through this decomposition, we reveal that lifetime separation is indeed driven primarily by the presence of the strange metal component. |
