Hysteresis Loop in Current-Voltage Curve for BaPb_0.7Bi_0.3O₃ Josephson Junction Array in a Microwave Field

Minoru Ito, Yoichi Enomoto and Toshiaki Murakami

Microwave-induced high dc voltage of a few millivolts across the unbiased BaPb_0.7Bi_0.3O₃ Josephson tunnel junction array is observed. A nearly rectangular hysteresis loop due to the voltage generation appears in current-voltage curve. The loop depends on load resistance, rf power and length and width of the sample. The induced voltage polarity can be easily switched by an external pulse current input signal of only 50 A/cm². This voltage switching can probably be exploited in the Josephson junction array as a future element.
