As propriedades dependentes do tamanho das junções Josephson intrínsecas em Bi2Sr2CaCu2Oy mesas de cristal único no campo magnético externo são estudadas. As mesas de (1-140) µm de comprimento com 7-29 junções foram fabricadas e suas características de corrente-tensão foram medidas em campo magnético externo aplicado paralelamente ao CuO2 camadas de até 0.16 T. No campo magnético zero, múltiplos ramos resistivos com grande histerese foram observados nas características de corrente-tensão para as mesas fabricadas. Correntes críticas quase idênticas também foram observadas para todas as junções em cada mesa. Com campo magnético aplicado, Ic das mesas mais longas mostraram uma dependência complexa do campo magnético em comparação com as mesas curtas (de cerca de 1 µm de comprimento). Observou-se que o campo magnético crítico inferior das junções diminuiu e aproximou-se de um valor constante com o aumento do número de junções e também com o aumento do comprimento das junções. Comportamento magnético semelhante foi obtido por simulações numéricas baseadas em equações seno-Gordon acopladas para tais junções empilhadas.

Abstract: The size dependent properties of the intrinsic Josephson junctions in Bi2Sr2CaCu2Oy single crystal mesas in the external magnetic field are studied. The mesas of (1-140) µm long with 7-29 junctions were fabricated and their current-voltage characteristics were measured in external magnetic field applied parallel to the CuO2 layers up to 0.16 T. In zero magnetic field, multiple resistive branches with large hysteresis were observed in the current-voltage characteristics for the fabricated mesas. Almost identical critical currents were also observed for all the junctions in each mesa. With applied magnetic field, Ic of the longer mesas showed a complex magnetic field dependence as compared to that of the short mesas (of about 1 µm in length). It was observed that the lower critical magnetic field of the junctions decreased and approached a constant value with increasing number of junctions and also with increasing length of the junctions. Similar magnetic behavior was obtained by numerical simulations based on coupled sine-Gordon equations for such stacked junctions.
