Ap. Dostanko et al., MINIMUM IN THE VOLTAGE-DEPENDENCE OF THE RESISTANCE OF THIN YBA2CU3O7-X MICROBRIDGES, Doklady Akademii nauk BSSR, 40(6), 1996, pp. 44-48
A differential resistance minimum at zero bias voltage was observed in
the characteristics of YBa2Cu3O7-x thin film microbridges of 10 mu m
in length (L) and 1 mu m in width (W), or L = 3 mu m and W = 2 mu m wh
ich had no supercurrent at the temperatures above 4,2K. Possible cause
s of the minimum appearance are discussed.
