Summary

Interactive course addressing bulk and thin-film magnetic materials that provide application-specific functionalities in different modern technologies such as e.g. wind energy harvesting, electric article surveillance, spintronics, sensing, and data storage.

Content

The course explains the relation between properties of magnetic materials and their composition, structure, as well as underlying preparation techniques.

  1. Introduction to magnetic phenomena
  2. Basic concepts of magnetic materials
  3. Fabrication and synthesis techniques (bulk materials, thin films, nanoscale materials)
  4. Electric, magnetic, mechanical, optical, and thermal properties depending on composition, structure, preparation technique
  5. Figure-of-merits of magnetic materials in different technologies and performance tests
  6. Applications (e.g. storage, electric article surveillance, sensors, spintronics)
  7. Abundance of relevant elements, sustainability
