Source data for: Giant negative magnetoresistance in tellurene driven by quantum geometry

This dataset contains the source numerical data supporting the figures and conclusions of the Nature Communications article “[INSERT FINAL TITLE]”, manuscript number NCOMMS-26-006253B. The archive includes Microsoft Excel spreadsheets containing the data used for the analysis of positive magnetoresistance (PMR), negative magnetoresistance (NMR), giant negative magnetoresistance (GNMR), angular-dependent magnetoresistance, gate-voltage-dependent response, temperature-dependent response, and fitting parameters used in the manuscript. The README file included in the archive describes the contents of each spreadsheet. PMR denotes positive magnetoresistance, NMR denotes negative magnetoresistance, GNMR denotes giant negative magnetoresistance, ang_dep_yz denotes angular dependence for a magnetic field confined to the yz plane, ang_dep_yx denotes angular dependence for a magnetic field confined to the yx plane, V_dep denotes gate-voltage dependence, and T_dep denotes temperature dependence.
