The chiral magnet MnSi, which crystallizes in the cubic B20 structure, has evoked much interest due to the existence of skyrmions. Furthermore the material shows an extended magnetic phase diagram when introduced to a reduction of the dimensionality of the system. Therefore it is of great interest to analyze nano-sized MnSi in form of thin films and nano wires.
We have grown high quality thin films via molecular beam epitaxy and structured them using electron beam lithography. Hall bar structures with widths between 100 nm and 10 µm have been produced and characterized regarding their structural properties. First measurements of the electrical and magnetical characteristics have been started. The results will be presented and deviations from three and two dimensional material will be discussed.
