Information

Aims, contents and method of the course

A disturbance in the local magnetic order can propagate in a magnetic material in the form of a wave. This wave was first predicted by F. Bloch in 1929 and was named a spin wave because it is related to a collective excitation of the electron spin system in magnetically ordered solid bodies. The quanta of spin waves are referred to as magnons. The field of science that refers to information transport and processing by spin waves is known as magnonics

The course gives an introduction to various aspects of spin-wave physics. The course contains the following topics: Basics of magnetism, magnetization precession and FMR, magnetic materials, dipolar and exchange spin waves, quantized spin waves, basics of microwave technique, and basics of magneto-optical techniques.

The course is designed for Students interested in experimental solid-state physics and beyond. In particular, magnetism and spintronics are in focus.

Assessment and permitted materials

The course will be assessed via a written examination. Course materials, textbooks, and smartphones will be allowed in the exam. The examination will focus on the understanding of spin-wave physical principles and phenomena.

Minimum requirements and assessment criteria

There are no special pre-requirements for taking part in this course. Participation in VO “Advanced Materials” in summer semesters or M-CORE 10 VO Condensed Matter Physics (2021W) is preferable but not obligatory. The course is also directly related to the LP Praktikum: Solid state physics: Materials and Methods for Bachelor's Students (in winter semesters) and LP Solid state physics: Research and Applications for Master's Students (in winter semesters).

The standard grating on the examination will be used:
50% of the total points at the final exam.
50 - 62.49% grade 4
62.5 - 74.99% grade 3
75 - 87.49% grade 2
87.5 - 100% grade 1
