Advantages of Spintronics
- 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 process
- 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
