Anomalous Change of Hall Coefficient in Overdoped La2−xSrxCu1−yZnyO4 around x = 0.2

The Hall coefficient (RH) has been measured in 0.5% Zn‐doped La2−xSrxCu0.995Zn0.005O4 under high magnetic fields up to 12 T. With decreasing temperature, RH increases and begins to decrease below a temperature TRH. This characteristic temperature TRH has the local maximum around x = 0.195, and this ... View More
