Materials for Data Storage and Mining Computing

Within our current wireless information society, there is an intense quest for new materials that can facilitate faster and more powerful computers along with high-density data storage. Further and even more importantly, the rather low energy efficiency of today’s electronics is becoming an increasing problem for achieving a sustainable society where e.g. server farms are consuming electrical energy comparable to medium sized cities. To obtain a paradigm shift within this important field, a transition away from current electronic devices that are based on, and limited by, the detection and movement of the electron charge. Instead the focus is now on utilization of the electron spin with the development of efficient spintronics and quantum technologies.

Neutron scattering is one of very few available experimental techniques that can directly study the magnetic spin structure and dynamics of novel materials. Consequently, neutrons are absolutely essential for understanding and developing a new generation of quantum materials and devices. Virtually the entire scope of neutron techniques is utilized to investigate and access fundamental magnetic properties of both bulk materials as well as thin films and multilayers. Such experimental characterization efforts are in most cases also naturally coupled to, and complemented by, both advanced materials synthesis (novel materials) along with theory and computer modeling to achieve a complete understanding of these exciting phenomena.

Sweden is currently building up a new generation of neutron scatterers and scientists that are ready to accept the challenge for realizing a future quantum society.
