Dependence with the amplitude of N = 80 × 103 square pulses (Vpulse ) of the remanent resistance of each contact (low state and high state for the Au and Pt interfaces, respectively). The Vpulse magnitude is different for each contact as it corresponds to their effective voltage drop. 100 μs pulses were applied at 1 kHz rate at a constant temperature (240 K). The high and the low states of these contacts obtained after applying are also shown for comparison. Lines are guides to the eye.
Relative variation of the remanent resistance of the Au-YBCO interface as a function of the amplitude of the reset pulses (Vpulse ) at different temperatures. The pulse treatment corresponds to (a) N = 60 × 103, (b) N = 100 × 103, and (c) N = 500 × 103 square pulses with the same characteristics described in the text. Lines are guides to the eye.
α as a function of the amplitude of the reset pulses (Vpulse ) at 260 K, varying the number N of applied pulses. Lines are guides to the eye.
Electric field stress lifetime curves (V-N curves) at 240 K, where the failure criteria corresponds to an arbitrarily value of α = 10% to 30%. Dotted lines are fits corresponding to Eq. (1) . Slash-dotted lines indicate two possible correction protocols to modify an obtained to a targeted (see text).
V-N curves at different temperatures for a failure criteria of 20%. Dotted lines are fits corresponding to Eq. (1) . As for cyclic mechanical stress experiments, lowering the temperature shifts the curves to higher voltage stresses.
