Abstract
Despite obvious similarities in their electronic and crystallographic structures, it remains unclear whether the interactions that shape the normal and superconducting (SC) state properties of high-Tc cuprates and infinite-layer nickelates (ILNs) have the same origin. This question has been brought into sharper focus with recent studies on ILNs of improved crystallinity that reveal a SC dome of comparable extent and similar transport properties above Tc as the hole-doped cuprates. The evolution of these properties in the magnetic-field-induced normal state, however, has yet to be determined. Here, we examine the magnetotransport properties of new-generation Nd1-xSrxNiO2 films in the T → 0 limit across the phase diagram in fields up to 54 T. This extensive study reveals that the limiting low-T form of the normal-state resistivity in ILNs exhibits non-Fermi-liquid behaviour over an extended doping range inside the SC dome, rather than at a singular quantum critical point. While there are clear differences in the charge dynamics of ILNs and cuprates, most notably in the magnetoresistance, our findings reveal that both systems exhibit anomalous metallicity characteristic of a quantum critical phase.

This dataset contains four Excel files with the raw data used to create the main figures in the manuscript. Variables accompanied by units are contained within the Excel worksheets. The contents of each data file are explained below.
NSNO_ZeroField:
In-plane resistivity (rho) as a function of Temperature (T) in zero applied magnetic field. The third row shows the doping level x of each sample. Note the resistivity here is in unit of micro-Ohm centimeter (uohm.cm).
NSNO_DC_FieldSweeps:
In-plane resistivity (rho) as a function of Magnetic field up to 34 T, at constant temperature values specified in the third row (in unit of K). Four tabs store data in the same format for 4 different doping levels (x=0.15, 0.175, 0.20, and 0.225). Note the resistivity values here are in unit of milli-Ohm centimeter (mohm.cm).
NSNO_DC_TempSweeps:
In-plane resistivity as a function of Temperature in zero and large magnetic field up to 34 T, as specified in the third row. Resistivity in zero and finite magnetic field shown here are measured using identical setup. Eight tabs store data in the same format for 8 different doping levels (x=0.175, 0.20, 0.225, 0.25, 0.275, 0.30, 0.3125, and 0.325). Note the resistivity here is in unit of micro-Ohm centimeter (uohm.cm).
NSNO_PulsedField:
In-plane resistivity as a function of Magnetic field in magnetic fields up to 53.7 T, at constant temperatures as specified in the third row. Three tabs store data in the same format for 3 different doping levels (x=0.15, 0.1625, and 0.175). Note the resistivity here is in unit of micro-Ohm centimeter (uohm.cm).
