Magnetic order in the normal state of the archetypal high-Tc superconductor La2-xSrxCuO4

Abstract

We report detailed bulk magnetization measurements of the normal state in the high transition temperature (high-Tc) superconductor La2-xSrxCuO4. A magnetic order in the form of hysteresis in the low field magnetization was observed at temperatures well above Tc but below the pseudogap temperature. The order arises from the interaction of magnetic domains, and the doping (x) dependence of its onset and strength broadly follows that of Tc(x).
