Abstract
The resistive properties of thin NbOx films above and below H-c2 were investigated experimentally. It was shown that in thin amorphous films the vortex pinning appears much below H-c2. The position of the vorte x pinning appearance moves up to H-c2 with film thickness increase and pinning value increase. A nonperturbative fluctuation theory of the m ixed state of two-dimensional type-II superconductor in the lowest Lan dau level (LLL) approximation is proposed.
