Magnonics - Lecture 5 - Quantised spin waves in confined structures

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.
