Researchers have, with the help of computer simulations, discovered a combination of materials that strengthens the so-called Friedel oscillations and bundles them, as if with a lens, in different directions. With a range of 50 nanometers, these 'giant anisotropic charge density oscillations' are many times greater than normal and open up new possibilities in the field of nanoelectronics to exchange or filter magnetic information.

Researchers have used high-speed photography to film one of the candidates for the magnetic data storage devices of the future in action. The film was taken using an X-ray microscope and shows magnetic vortices being formed in ultrafast memory cells. Their work provides a better understanding of the dynamics of magnetic storage materials.

Ultra-short and extremely strong X-ray flashes are used by researchers to take 'snapshots' of the geometry of tiniest structures, for example the arrangement of atoms in molecules. To improve not only spatial but also temporal resolution further requires knowledge about the precise duration and intensity of the X-ray flashes. An international team of scientists has now tackled this challenge.
