Abstrakt: | In this work studies of structure and superconducting properties of VN SiO2 lms are reported. The lms were obtained through thermal nitridation (ammonolysis) of sol gel derived V2O3 SiO2 coatings (in a proper V2O3/SiO2 ratio) at 1200 ◦ C. This process leads to the formation of disordered structure with VN metallic grains dispersed in the insulating SiO2 matrix. The structural transformations occurring in the lms as a result of ammonolysis were studied using X-ray photoelectron spectroscopy (XPS). The critical superconducting parameters are obtained. The magnetoresistance at high magnetic elds has been investigated. |
