Anomalous structure in doping level dependence of normal resistivity of La"2"-"xSr"xCuO"4 - Sugahara, M.; Jiang, J.-F. (Elsevier)
We experimentally studied the anomaly found in the doping level x dependence of the normal resistivity of carefully made bulk samples of La"2"-"xSr"xCuO"4 in 0〈x〈0.45. The general feature of (x) is decreasing function in 0〈x〈0.25 (hole region), and increasing function in 0.25〈x〈0.45 (electron region). Clear depressions of appear in series on singular levels x=x"n in hole region and on x=y"n in electron region (n, integer). where the separations between them are ΔX"nx"n-x"n+1~14^n-14^n^+^1 and ΔY"ny"n+1-y"n~(14^n-14^n^+^1)2.
