An experimental physicist who coauthored a 2004 report of large room-temperature tunnelling magnetoresistance in iron electrodes separated by a crystalline magnesium-oxide barrier. Changing the relative magnetic alignment changes electrical electrical resistance, allowing a magnetic configuration to be read electrically. The work connects controlled crystalline interfaces with devices that use electron spin as well as charge.[ref]
