Plasma fabrication of BiSrCaCuO superconductive films and non-superconductive NiFeO for hybrid devices

We report new results on plasma fabricated BiSrCaCuO superconductive films and non-superconductive NiFeO for hybrid devices. This fabrication process takes place in an atmospheric environment and involves four steps: solution preparation, mist generation, vapor production, and cluster deposition. Among all deposition parameters, substrate temperature is the most important parameter to affect the phase formation in BiSrCaCuO films. The zero resistance temperature is 105 K for an as deposited 2223 film, and 78 K for 2212. The average crystallite size of non-superconductive NiFeO powders is approximately 35 nm, which can be utilized in hybrid devices. Mössbauer and magnetization measurement results will be given along with XRD and EDS analyses.
