We have fabricated c-axis Josephson junctions on single crystals of(Ba,K)Fe2As2 by using Pb as the counter electrode in two geometries, planar andpoint contact. Junctions in both geometries show resistively shunted junctionI-V curves below the Tc of the counter electrode. Microwave induced steps wereobserved in the I-V curves, and the critical currents are suppressed with anin-plane magnetic field in a manner consistent with the small junction limit.ICRN products of up to 0.3 mV have been observed in these junctions at 4.2 K.The observation of Josephson coupling along the c-axis between (Ba,K)Fe2As2 anda conventional superconductor suggests the existence of a s-wavesuperconducting order parameter in this class of iron pnictide superconductors.
