Movies
E. Y. Vedmedenko Dipole Model See the effect of an external field on a model of point dipoles on a square lattice (i.e. the ground state is degenerated).
  Multipole Simulation See a simulation of Dipole-Octopole switching in an external field. Apart from the additional octopole moment  it's like the above simulation. Hence, the third-order moment forces row-wise switching resulting in a non-zero coercive field.
  Disc of dipoles I Monte Carlo simulation of dipoles on a disc with kBT=0.9 J, i.e. above TC. Observe the long time correlation in the perpendicular magnetisation.
  Disc of dipoles II Like the one above but with kBT=0.1 J. The simulations starts directly after decreasing the temperature (higher disorder).  While most of the spins loose their fluctuations and go more in-plane, the vortex core goes out-of-plane.
 
Mathematica
N. Mikuszeit Package Collection This archive contains several functions, which should make life a little bit easier.
  DisplayMultipoles functions to display arrays of individually rotated spherical harmonics; for Mathematica 5.2 (5.5 MB).
  DisplayMultipoles functions to display arrays of individually rotated spherical harmonics; for Mathematica 6.0 (2.5 MB).
  Example Notebooks To explain the packages.
  Self-EnergyOfChargedTrapezoid Integration of the Poisson equation to get the self-energy of a homogeneously charged trapezoid.

Mathematica fast binary This is a Mathlink program for a fast import/export of binary data into Mathematica.
As reading of binary data is implemented in version 5.1 or higher, this program is only required for older versions, as the binary package was really slow, though it still runs under version 5.2 without problems.
