Spintronics Seminar and PPT with PDF Report: Ceremonious electronic devices neglect the spin property and rely rigorously on the transport of the electrical charge of electrons.

Spintronics Seminar PDF Report and PPT

Advantages of Spin

  • Information is reserved into spin as one of two possible orientations
  • Spin lifetime is relatively long, on the order of nanoseconds
  • Spin currents can be manipulated
  • Magnetic storage is nonvolatile

Spin Transfer

  • Current passed through a charismatic field becomes spin polarized
  • This flipping of magnetic spins applies a big torque to the magnetization within the outside magnet
  • This torque will pump energy to the magnet causing its charismatic moment to precess
  • Unwanted effect in spin valves
  • Possible applications in memory writing

Magnetic Semiconductors

  • Materials like magnetite are magnetic semiconductors
  • Development of materials similar to conventional
  • Research aimed at dilute magnetic semiconductors
    • Manganese is commonly doped onto substrate
    • However previous manganese-doped GaAs has transition temp at -88oC
  • Curie temperatures above room must be produced

Current Research

  • Weitering et al. have made numerous advances
    • Ferromagnetism in Mn doped group IV semiconductors.
    • Room temperature ferromagnetism in (Ga,Mn)N, (Ga,Mn)P, and digital-doped (Ga,Mn)Sb.
    • Large magnetoresistance in ferromagnetic semiconductor tunnel junctions.
  • Material science
  • Many methods of charismatic doping
  • Spin transport in semiconductors
