micromagnetic simulation

High symmetry gadolinium(III) polyhedra

In a recent article, creation of hollow nanospheres Gd20, Gd32, Gd50 and Gd60 is described using the approach to assemble fragments containing different polygons. While structural analysis revealed the symmetries of the respective nanospheres, magnetic studies show in theory and experiment that these polyhedra show antiferromagnetic interaction which can be attributed to classical spins at the Gd sites. Magnetic measurements can even be used as "fingerprints" to identify the polyhedra.

Magpar for beginners - a tutorial

Installation of parallel-computing Magpar micromagnetic simulator is a very challenging task for all interested physicists, and scientists in general, for whom computer science experience is from natural reasons very poor, especially within Unix-like systems. In the following report the reader can find step-by-step information how to install Magpar in Linux-based system. Since Magpar was issued in 2010, many details about location of files are not actual today.
