Magnetic vortices

Magnetic vortices are curling magnetization structures formed in micro- and nanosized magnetic disks and polygons. They are known for having four different magnetization configurations (vortex states) that can be used for a multibit memory cell. We study dynamic magnetization processes of switching of the vortex states and we investigate the possibilities of writing two bits of information into a magnetic vortex.

Magnetic patterning by direct focused ion beam writing

Direct writing of magnetic patterns by focused-ion-beam irradiation presents a favorable alternative to the conventional lithography approaches. We study epitaxially grown metastable face-centered cubic (fcc) Fe thin films which undergo structural (fcc->bcc) and magnetic (paramagnetic->ferromagnetic) phase transformation upon ion-beam-irradiation. By using focused ion beam we were able to write ferromagnetic (bcc Fe) patterns into the paramagnetic (fcc Fe) layer with sub-100 nm resolution.
