Content, Learning Outcome and Preconditions

Content

Based on the fundamental knowledge of magnetism thies module studies recent developments in magnetism with a focus on spintronics.

The following subjects will be covered:

  • magnetism and domain formation in ultra thin films
  • spin transport in nanostructures and spin transport across interfaces
  • spin transfer torque based current-induced domain wall motion
  • spin transfer torque based magnetic switching
  • magnetization dynamics on picosecond timescales described by the Landau-Lifshitz-Gilbert equation of motion

Learning Outcome

After successful completion of the module the students are able to:

  • understand domain formation in ultra thin films and the spin reorientation transition
  • describe the equation of motion for the magnetization
  • understand spin transport in magnetic nanostructures
  • explain spin transfer torque and current induced magnetization dynamics

Preconditions

Successful completion of the module PH2033: Magnetism or PH2265: Magnetism and magnetic materials is recommended.

Module Exam

Description of exams and course work

There will be an oral exam of 25 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and sample calculations.

For example an assignment in the exam might be:

  • Explain the domain formation in ultra thin films.
  • What is the origin of the spin reorientation transition in ultra thin films?
  • Describe the precessional switching.
  • Describe the current-induced domain wall motion.

Exam Repetition

The exam may be repeated at the end of the semester.
