Content, Learning Outcome and Preconditions

Content

In this module, an overview over the physics and technology of modern magnetic measurement techniques is given. After an introduction to the basics of magnetism and the generation of magnetic fields in the laboratory, different magnetic measurement techniques are introduced in context with relevant scientific questions. These questions address the experimental determination of, e.g., Fermi surfaces using torque magnetometry, domain structures in magnetic recording media using Magnetic Force Microscopy, magnetization dynamics using the magneto-optical Kerr effect or the arrangement of atomic magnetic moments on solid-state surfaces detected by spin-polarized scanning tunneling microscopy. The underlying physical principles and the technological realizations of the measurement methods are highlighted. The physics of the magnetic phenonema under investigation as well as the physics of the relevant measurement technique are discussed with a focus on the basic physical aspects in this area of experimental physics. Current scientific developments in these topical area are considered in this module.

Learning Outcome

After successful participation in this module the student is able to:

  1. understand and explain different concepts of magnetic systems and the effects of magnetic fields on different solid-state systems;
  2. understand and explain the physical aspects of magnetic measurement techniques, in particular the interaction between measurement object and sensor;
  3. describe and explain the technical implementation of different magnetic measurement techniques;
  4. judge the spatial and temporal resolution capability of magnetic measurement techniques.;
  5. select and to sketch experimental setups relevant for the investigation of physical questions in magnetism;
  6. name the different time- and length scales relevant to magnetic phenomena;
  7. describe the consequences of band structure effects and dimensionality of a solid state system for its magnetic properties
  8. develop a scientific theme with guidance, to create a presentation and to give a talk as well as to judge presentation techniques and to apply them.

Module Exam

Description of exams and course work

In an oral exam the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 60 minutes.

Exam Repetition

There is a possibility to take the exam at the end of the semester. There is a possibility to take the exam in the following semester.

Condensed Matter

When atoms interact things can get interesting. Fundamental research on the underlying properties of materials and nanostructures and exploration of the potential they provide for applications.

Nuclei, Particles, Astrophysics

A journey of discovery to understanding our world at the subatomic scale, from the nuclei inside atoms down to the most elementary building blocks of matter. Are you ready for the adventure?

Biophysics

Biological systems, from proteins to living cells and organisms, obey physical principles. Our research groups in biophysics shape one of Germany's largest scientific clusters in this area.
