Image analysis : Delaunay triangulation to predict FMR linewidth

Posted onLeave a comment

The problemLet’s consider a polymer sheet, 50 µm thick, where very small holes (~ 50 nm) are randomly distributed. When these holes are filled, this system becomes an array of nanowires embedded in a polymer template.If the holes are filled with a magnetic materiel (e.g. Cobalt, Iron) the array can be analyzed by ferromagnetic resonance Read More …

Automatic estimation of magnetic domain wall propagation

Here is an image analysis script I have recently written on my spare time for my friends at the national science research center (CNRS). The short storyWe consider a magnetic nano-structure submitted to magnetic and/or electric field. Upon proper conditions, the magnetic state of the structure will evolve and switch from one polarity to the Read More …
