✦ Synopsis

The resistive properties of thin NbO, films above and below H~2 were investigated experimentally, it was shown that in thin amorphous films the vortex pinning appears much below H~> The position of the vortex pinning appearance moves up to He2 with film thickness increase and pinning value increase. A nonperturbative fluctuation theory of the mixed state of two-dimensional type-II superconductor in the lowest Landau level (LLL) approximation is proposed.

The local density of states of low energy electronic excitations in a vortex is investigated. Starting from the Bogoliubov Hamiltonian, we make the approximation of replacing the quadratic momentum dependence of the free particle kinetic energy by a linear dependence. We then work with a linearized
