Linear Magnetoresistance Near Critical Doping In $La_{2-x}Sr_xCuO_4$

ORAL

Abstract

The strange metallic state in high-temperature superconductors is characterized by anomalous transport behavior, such as linear-in-temperature resistivity over a broad temperature range. It has recently been shown that anomalous dynamics near critical doping can be probed by strong magnetic fields. We report resistivity measurements at high magnetic fields in micro-structured $La_{2-x}Sr_xCuO_4$ single crystals in the doping range near critical doping. In particular, we discuss the angular dependence of the magnetoresistance near quantum critical point.
