Theory of Josephson effects in heterotic S-I-S junctions with iron-pnictide superconductors

Ota, Yukihiro; Machida, Masahiko  ; Nakai, Noriyuki; Nakamura, Hiroki  ; Koyama, Tomio*; Matsumoto, Hideki*

In order to examine pairing symmetry and application potential of iron-pnictide superconductors, Josephson junctions including the new type of superconductors have been intensively examined. In particular, recent experimental achievements indicate the necessity of further theoretical investigations for how multiple tunneling contributions and the sign change between the superconducting gaps reflect the basic Josephson effects. In this paper, we theoretically examine a $$I_{rm c}R_{rm n}$$ product and a Shapiro step in a heterotic SIS junction between conventional s-wave and iron-pnictide superconductors as a typical example of Josephson junctions with multiple tunneling channels. Then, we show that they are good probe to identify the pairing symmetry of the iron-pnictide superconductors.
