8 Spintronics — Spin - Based Electronics
Spintronics is an acronym for a spin transport electronics and was originally used as a name for the Defense Advanced Research Projects Agency (DARPA) program. In 1994, DARPA started to develop magnetic field sensors and memory based on the giant magnetoresistance (GMR) effect and spindependent tunneling. The overall goal for the Spintronics program was to create a new generation of electronic ...
متن کامل12 Materials for Spin Electronics
Materials which are currently used in spin electronic devices, and materials which may be useful in future are discussed. These include ironcobaltand nickel-based alloys for spin polarization and analysis, metallic and insulating antiferromagnets for exchange bias and oxides for tunnel barriers. The 3d alloys also serve as detection or sensor layers. Permanent magnet materials play a role in bi...
متن کاملQuantum Computation and Spin Electronics
1 In this chapter we explore the connection between mesoscopic physics and quantum computing. After giving a bibliography providing a general introduction to the subject of quantum information processing, we review the various approaches that are being considered for the experimental implementation of quantum computing and quantum communication in atomic physics, quantum optics, nuclear magneti...

متن کاملCaB6: a new semiconducting material for spin electronics.
Ferromagnetism was recently observed at unexpectedly high temperatures in La-doped CaB6. The starting point of all theoretical proposals to explain this observation is a semimetallic electronic structure calculated for CaB6 within the local density approximation. Here we report the results of parameter-free quasiparticle calculations of the single-particle excitation spectrum which show that Ca...
