Nanowerk  April 13, 2023 The discovery of van der Waals (vdW) magnets opened a new paradigm for condensed matter physics and spintronic technologies. However, the operations of active spintronic devices with vdW ferromagnets are limited to cryogenic temperatures, inhibiting their broader practical applications. Researchers in Sweden have demonstrated robust room-temperature operation of lateral spin-valve devices using the vdW itinerant ferromagnet Fe5GeTe2 in heterostructures with graphene. They measured room-temperature spintronic properties of Fe5GeTe2 at the interface with graphene with a negative spin polarization. Lateral spin-valve and spin-precession measurements provided unique insights by probing the Fe5GeTe2/graphene interface spintronic properties via spin-dynamics measurements, […]
