Data for Linear-in temperature resistivity from an isotropic Planckian scattering rate

The angle-dependent magnetoresistance shows a well defined Fermi surface that agrees quantitatively with angle-resolved photoemission spectroscopy measurements7 and reveals a linear-in-temperature scattering rate that saturates at the Planckian limit, namely α = 1.2 ± 0.4. Remarkably, we find that this Planckian scattering rate is isotropic, that is, it is independent of direction, in contrast to expectations from ‘hotspot’ models8,9.

Our findings suggest that linear-in-temperature resistivity in strange metals emerges from a momentum-independent inelastic scattering rate that reaches the Planckian limit.<br><br>The archive contains the experimental data from the following figures: Figure 2a Extended Data (ED) Figure 1b Extended Data (ED) Figure 5a The rho_xx and rho_zz data shown in Figure 3 are published in DOI: 10.1016/j.physc.2009.11.073 DOI: 10.1038/NPHYS1109 Data are listed in the archive as follows Fig??_HxxTyyphizz.dat where ?? = the figure number, xx = the applied magnetic field value in Tesla, yy = the sample temperature in kelvin, and zz = the azimuthal angle in degrees.
