In collaboration with colleagues from the Leibniz Institute for

University of Glasgow, physicists from the Helmholtz-Zentrum
Dresden-Rossendorf (HZDR) are working to produce engineered
magnetic nanostructures and to tailor material properties at the
nanoscale. The scientists use a special microscope at the HZDR
Ion Beam Center to achieve this goal. This microscope's ultrathin
ion beam can produce stable, periodically arranged nanomagnets in a sample material. The device can also be used to optimize the magnetic properties of carbon nanotubes.

in the embedded nanomagnets however, transverse magnetization components are also observed. The net effect is that the

"The magnetic tuning of materials in the nanometer range offers
great potential to produce state-of-the-art electronic components.

alloy then rearrange, thereby increasing the number of adjacent
magnetic iron atoms. As a result, a magnet is formed within the
vicinity of the bombardment site. This approach enabled the

In their latest work, the HZDR scientists demonstrate that the
ion-beam-induced disorder also increases the volume of the
underlying lattice structure, albeit not evenly in all spatial directions. The lattice distortion also affects the magnetic behavior.
For instance, in an elongated magnetic stripe, the magnetization
