SK3710 Spin Electronics 8.0 credits

Spinnelektronik

Spin electronics (also called magneto electronics or spintronics) is a new field of research combining two traditional branches of physics: magnetism and electronics. Electrons are tiny magnets as well as elementary charged particles, yet for 50 years conventional electronics has ignored the spin of the electron. Distinguishing and manipulating the spin-up and spin-down currents through nano-scale structuring of magnetic materials is expected to add a new dimension to the practice of electronics. The aim of this course is to give an introduction to magnetism and transport in magnetic nano-structures. A special emphasis will be made on applications in future spin-based memory and logic.

Intended learning outcomes

The overall aim in this course is to understand the physical principles of magnetism and transport in nanostructures with a special emphasis on applications in spin-based memory and logic. A progressively better understanding means that after the course you are able to:

  • identify different kinds of magnetism in solids, calculate the basic microscopic electronic parameters of materials given the necessary macroscopic characteristics, describe and calculate the main characteristics of the spin transport effects;
  • compare/contrast materials with regards to their magnetic and transport properties, explain the causes of the main spin transport effects, analyze their relevance in relation to technological applications;
  • theorize about the origins of magnetism and transport in solids aiming hypothetically at the ideal material(s) for spintronics, generalize device concepts as relates to spin transport, using the knowledge acquired in the course speculate about new transport devices based on spin.

Course main content

  • Normal and ferromagnetic metals
  • Basic electron transport
  • Giant Magnetoresistance
  • Spin dependent tunneling
  • Micromagnetic spin structure
  • Electronic noise in magnetic materials and devices
  • Materials for spin electronics: thin film and nano-fabrication techniques
  • Spin-transfer torques, current induced switching
  • Spin transport in semiconductors
  • Spin-valve and spin-tunnel devices in data storage, Magnetic RAM, sensors.
