Evolution of Magnetic Fields in Galaxies with Spiral Structure
3 S u m m a r y : We present simulations of the 3D nonlinear induction equation in order to investigate the temporal evolution of large-scale magnetic elds in spiral galaxies. Our model includes diierential rotation, ambipolar diiusion and, based on small-scale turbulence, eddy diiusivity and the tensorial-eeect with magnetic feedback. The nonax-isymmetric spiral pattern and { if considered { t...
متن کاملVortex structure around a magnetic dot in planar superconductors.
The problem of the giant vortex state around a magnetic dot which is embedded in a superconducting film is investigated. The full non-linear, selfconsistent Ginzburg-Landau equations are solved numerically in order to calculate the free energy, the order parameter of the host superconductor, the internal magnetic field due to the supercurrents, the corresponding current density, the magnetizati...
متن کاملShielding with superconductors in small magnetic fields
2014 The shielding properties of a superconducting lead shell have been investigated in fields of the order of 10-4 gauss. The small ambient fields were obtained with a room size 03BC-metal shield. Fields of less than 2 microgauss were obtained over a sphere of 7.5 cm diameter. This region is at room temperature and is suitable for magnetometer testing.

متن کاملBerry phase in magnetic superconductors.
In magnetic systems, electronic bands often acquire nontrivial topological structure characterized by gauge flux distribution in momentum k space. It sometimes follows that the phase of the wave functions cannot be defined uniquely over the whole Brillouin zone. In this Letter, we develop a theory of superconductivity in the presence of this gauge flux both in two- and three-dimensional systems...
