3-D imaging: First insights into magnetic fields
3-D images are not only useful in medicine; the observation of internal structures is also invaluable in many other fields of scientific investigation. Recently, researchers from the Hahn-Meitner-Institute (HMI) in Berlin in cooperation with University of Applied Sciences in Berlin have suc ... more
Nanopatterns Regulate Electricity
Regular arrangements of sodium atoms make sodium cobalt oxide a perfect material for laptop batteries, an efficient cooling material and a superconductor. The concentration of sodium atoms in the material can vary and the material's behaviour depends sensitively on this number. Scientists f ... more
Long-lived magnetic fluctuations in a crystal
One of the most familiar magnetic materials is magnetized iron. Much of the observed behaviour of iron and related magnetic materials can be understood using existing theoretical results. However, due to limitations of the experimental techniques that were previously available, important ch ... more
