- Title
Magnetic Field Penetration into Half-Space for Type-II Superconductors of the Second Kind.

- Abstract
Equations that simulate the magnetic induction and current density distributions in half-space in view of the power I–V characteristic are derived. The magnetization front velocity is determined for a given mean rate of external magnetic field variation at the boundary of the sample. An integral condition for the electrical resistance (nonlinearly depending on the magnetic field) under which the magnetic flux penetrates into the sample with a finite rate is found. An analytical solution that simulates the power variation of the magnetic field at the boundary is given. The Bean generalized model describing the current density distribution near the critical current is considered. It is shown that solutions like shock waves may arise beyond the applicability domain of the Bean model. © 2003 MAIK “Nauka / Interperiodica”.
