Scientists of the Research Centre Jülich, Germany, have found a fundamentally new magnetic switching method which achieves the fastest speed ever reported by applying an external magnetic field. The results that are presented in a current article in the scientific journal Physical Review Letters could introduce new possibilities for future data storage applications with ultimate speeds.

Besides its extremely high speed, a remarkable aspect of this finding is that it unfolds automatically: The applied field only perturbs the magnetization, which then under-goes these complicated changes as it recovers equilibrium. “These findings represent a promising leap towards smaller length scales and shorter time scales in magnetic data storage applications”, affirms Prof. Claus M. Schneider, director at the IFF
