Introduction to magnetic materials in modern technologies

MSE-432

Lecturer(s) :

Grundler Dirk

Language:

English

Summary

Interactive course addressing bulk and thin-film magnetic materials that provide application-specific functionalities and are relevant for modern technologies ranging from e.g. wind energy harvesting via electric article surveillance to 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, biocompatibility)

7. Abundance of relevant elements, sustainability

Keywords

Spontaneous magnetism, magnetism of elements and alloys, invar, ferro-, ferri- and antiferromagnetic, saturation magnetization, magnetic anisotropies, stray field, demagnetization effect, reversible and irreversible reversal processes, hysteresis, domain walls, dc and ac magnetic susceptibility, exchange interaction, dipolar forces, Ising model, Landau-Lifshitz-Gilbert equation and spin dynamics, magnetoelastic coupling, exchange bias, Delta-E effect, heat-assisted recording, hard and soft magnets, magnetoelectronics (spintronics), magnetooptics
