Abstract

Transport and Tc anomalies around x = 0.22 in La2-xSrxCuO4 have been studied through the partial substitution of Zn, Ga and Ni for Cu. It has been found that the value of x where the anomalies occur shifts to lower x values through the Zn substitution, while it shifts to larger x values through the Ga substitution, and it disappears through the Ni substitution. There is a possibility that an order of holes and/or spins, such as the so-called stripe order, is formed or fluctuates around x - 0.22 in La2-xSrxCuO4.
