in this work studies of structure and superconducting properties of vnsio2 films are reported. the films were obtained through thermal nitridation (ammonolysis) of solgel derived v2o3sio2 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 fields has been investigated.
