| Popis: | We study interactions of perpendicular and longitudinal magnetic fields in niobium films of different thickness in a wide range of temperatures below the superconducting transition temperature (TC). In 100-nm Nb film at all temperatures the longitudinal field H|| practically does not influence the dynamics of the normal flux. However, in 200-nm Nb film, a considerable anisotropy in the vortex motion is found with advanced propagation of the normal flux along H|| atT >TC /2 and the preferential jumpwise growth of the thermomagnetic flux dendrites across H|| atT |
