(a) Schematic of Au/SrRuO3/Sr2RuO4 junctions. Note that a ≈ 30-nm thick neck of SRO214 was prepared in order to separate a part of superconductor from the bulk substrate. (b) Temperature dependent resistance R(T) from 300 K down to 2 K for Junction J1 with the junction area of 20 × 20 μm2. Inset shows R(T) close to the superconducting transition. (c) R(T) of Junction J4 (5 × 5 μm2) at various applied currents. Vertical solid line indicates the bulk Tc of SRO214. Inset shows R(T) of the SRO214 substrate measured by using a four probes technique. (d) Current-voltage curves below and above Tc of Junction J4.
