Summary on Grant Application Form |
|
Type II superconductors (such as the new high temperature superconductors) ability to carry a dissipation free electric transport current in a magnetic field is determined by the properties of the magnetic vortex system inside the superconductor induced by the external magnetic field. As soon as the vortex system starts to move energy is dissipated and the superconductivity lost. The motion of the vortices can be hindered by inhomogeneities, acting as pinning centres, in the superconductor. The present project investigates, especially by use of computer simulations, the dynamical as well as the thermodynamical properties of the vortex system in a random pinning potential. The effect of thermal induced vortex pairs will also be studied. Detailed simulations are expected to be able to help to bridge the gap between theoretical models of flux pinning and experiments.
