August 2014 cover of Nature Materials, featuring Imaging of spin waves in atomically designed nano magnets by Spinelli et al. November 2016 cover of Nature Nanotechnology, featuring A kilobyte rewritable atomic memory by Kalff et al.

Please have a look at our YouTube movie, demonstrating how to manipulate atoms on copper-nitride. Using this technique we have been able to construct, among others, the following assemblies:


Two chains of each 7 iron atoms, one antiferromagnetic (top) and one ferromagnetic (bottom left).

Antiferromagnet consisting of 15 iron atoms, measured with a spin-polarized tip (similar to Loth et al., Science 335, 196 (2012))

Chains of various lengths made of cobalt atoms on copper nitride on Cu(100).
