Electrical spin filtering avoids energy-costs of magnetic field — ScienceDaily

Spin-filtering could be the key to faster, more energy-efficient switching in future spintronic technology, allowing the detection of spin by electrical rather than magnetic means. A UNSW paper published last month demonstrates spin detection using a spin filter to separate spin orientation according to their energies. Ultra-fast, ultra-low energy ‘spintronic’ devices are an exciting, beyond-CMOS […]
