摘要：

We report the engineering of sets of mesas on lead-substituted single crystals of Bi2Sr2CaCu2O(y). Each mesa behaves as a series array of intrinsic Josephson junctions with, up to 70 K, ''two states'' hysteretic I(V) characteristics, free of branching, whose R(n)I(c) products can be tuned through geometrical patterning and adjustment of the lead contents. R(n)I(c) values as high as 550 mV at 4.2 K have been reached. The tuning through lead substitution is attributed to the decrease of the anisotropy with increasing lead content.
