In this study we investigate Josephson junctions with ferromagnetic Ni as a barrier. The aim of the study is to characterize the junctions from point of view Josephson coupling. We study the thickness dependence of the critical current into a wide range of thicknesses of the ferromagnetic barrier(0-35nm). We see Josephson coupling at high thicknesses of 35nm which open the possibility of building and controlling device based on strong ferromagnetic Josephson junctions. A threshold thickness has been observed at around 4nm where Fraunhofer modulation of the critical field disappears. We attribute the threshold behavior to the physical continuity of ferromagnetic layer. We fabricate and study junctions at different nanoscaled geometries and we investigate the magnetic properties of the ferromagnet based on the electrical properties of the Josephson Junction. The layers were deposited by physical sputtering and the variation of the thickness of the barrier has achieved by angled deposition. The ferromagnetic barrier is sandwiched between two superconductor layers of the niobium, each 200nm thickness. The junctions are fabricated by FIB (Focused Ion Beam) with geometries in the hundreds of nanometers. The system will allow the future study of Josephson junctions based on strong ferromagnet spin valves. The spin valve Josephson junction would allow the study of triplet superconductivity and the integration of a wide range of spintronic devices into Josephson junction.
