Title: Transport and {Tc} anomalies around x = 0.22 in La{sub 2{minus}x}Sr{sub x}Cu{sub 1{minus}y}M{sub y}O{sub 4} (M = Zn, Ga, Ni): Possibility of charge and/or spin ordering

Abstract

Transport and {Tc} anomalies around x = 0.22 in La{sub 2{minus}x}Sr{sub x}CuO{sub 4} 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 La{sub 2{minus}x}Sr{sub x}CuO{sub 4}.
