Magnetic Skyrmion Materials for Ultralow Energy Memory

Back to search results
All computer memories work by switching between two distinct entropy states using an external stimulus. Control over the switched area and the switching time determines the achievable information storage density and the device performance. Therefore, reducing the switching area with relatively fast switching times (~1 ns) and reduced losses will lead towards a universal memory device for replacing conventional RAM and magnetic hard drives. In this context, the recent observation of nanometre sized particle-like stable spin configurations, known as skyrmions, have provided a pathway for the realisation of such universal memories which are expected to be 100 times cheaper than the conventional RAM and a million times faster than magnetic hard drives. This project aims at finding ideal materials for this purpose and at developing the best mechanisms for skyrmion manipulation, thus facilitating the discovery of a universal memory device for a new era of information storage.
