Bose-Einstein condensate: Magnetic particles behave repulsively

Data transmission that works with magnetic waves instead of electric currents can be the basis for future information technologies. Some years ago, researchers at Münster University (Germany) reached a new quantum state of magnetic particles at room temperature — a Bose-Einstein condensate. In a new study they show that the particles in the condensate behave repulsively, which leads to its stabilization. In this way, they resolve a long-standing contradiction between the theory and the experiment.
