Quantum criticality in La$_{\mathrm{2-x}}$Sr$_{\mathrm{x}}$CuO$_{\mathrm{4\thinspace }}$cuprates probed with high magnetic fields.

Abstract

We report magnetoresistance measurements at high magnetic fields, up to 80T, in thin-film La$_{\mathrm{2-x}}$Sr$_{\mathrm{x}}$CuO$_{\mathrm{4\thinspace }}$cuprates. At very high fields the resistivity is found to have a linear-in field behavior that mirrors the linear-in temperature behavior at high temperatures. We discuss the implications of linear-in-field magnetoresistance for energy scale competition near quantum critical point in high-temperature superconductors.
