  • Opportunities and challenges for spintronics in the microelectronics industry
  • 2020
  • Ingår i: Nature Electronics. - : Springer Science and Business Media LLC. - 2520-1131. ; 3:8, s. 446-459
  • Tidskriftsartikel (refereegranskat)abstract
    • This Review Article examines the potential of spintronics in four key areas of application -memories, sensors, microwave devices, and logic devices - and discusses the challenges that need be addressed in order to integrate spintronic materials and functionalities into mainstream microelectronic platforms. Spintronic devices exploit the spin, as well as the charge, of electrons and could bring new capabilities to the microelectronics industry. However, in order for spintronic devices to meet the ever-increasing demands of the industry, innovation in terms of materials, processes and circuits are required. Here, we review recent developments in spintronics that could soon have an impact on the microelectronics and information technology industry. We highlight and explore four key areas: magnetic memories, magnetic sensors, radio-frequency and microwave devices, and logic and non-Boolean devices. We also discuss the challenges-at both the device and the system level-that need be addressed in order to integrate spintronic materials and functionalities into mainstream microelectronic platforms.

  • Chiral charge pumping in graphene deposited on a magnetic insulator
  • 2017
  • Ingår i: Physical Review B. - 2469-9969 .- 2469-9950. ; 95:2
  • Tidskriftsartikel (refereegranskat)abstract
    • We demonstrate experimentally that a sizable chiral charge pumping can be achieved at room temperature in graphene/yttrium iron garnet (YIG) bilayer systems. The effect, which cannot be attributed to the ordinary spin pumping, reveals itself in the creation of a dc electric field/voltage in graphene as a response to the dynamic magnetic excitations (spin waves) in an adjacent out-of-plane magnetized YIG film. We show that the induced voltage changes its sign when the orientation of the static magnetization is reversed, clearly indicating the broken mirror reflection symmetry about the planes normal to the graphene/YIG interface. The strength of effect shows a nonmonotonous dependence on the spin-wave frequency, in agreement with the proposed theoretical model.
