Magnetic memory states go exponential (IMAGE)
Caption
Researchers from Bar-Ilan University have shown that relatively simple magnetic thin film structures of N crossing ellipses can support two to the power of 2N magnetic states - much greater than previously thought - and demonstrated switching between the states with spin currents. The ability to stabilize and control exponential number of discrete magnetic states in a relatively simple structure constitutes a major contribution to spintronics and may pave the way to multi-level magnetic memory with extremely large number of states per cell, be used for neuromorphic computing, and more. The image shows examples of simulated magnetic states supported by the structures.
